What is its functional group ?

Functional group:

$-OH$ or alcoholic group

The correct IUPAC name of the compound shown is

Hint: Select the longest continuous chain starting from the carboxylic acid end.

Explanation:

The numbering will start from the most priority group $COOH$ .

Two $COOH$ groups are present so $-dioic \ acid$

An ethyl group is present at $C-2$ position and methyl at $C-4$ position. So, It will be $2-ethyl$ and $4-methyl$ .
Here we are not giving numbering from the other $COOH$ group because if we compare ethyl and methyl then according to alphabetical order $Ethyl (E)$ comes first and then $Methyl (M)$

So, the name of the compound is- $2-ethyl-4-methyl-pentane-1,5-dioic acid$ .

Correct Answer : $2-ethyl-4-methyl-pentane-1,5-dioic acid$

The correct IUPAC name is $H_3C - CH_2 - O - \overset{CH_3}{\overset{\!\!\!\!\!|}{CH}} - CH_2 - CH_2 - CH_2 Cl$

The functional group is a group of an atom within a molecule which is responsible for chemical characteristics of that molecule (compound). The first carbon atom after the carbon atom bonded to a functional group is known as alpha carbon and further carbon in a chain are known as beta, gamma progressively. Homologous series is a series of organic compounds with a similar formula, possessing similar chemical properties due to the _______ of the same functional group.

For the naming of carbon as alpha, beta and gamma there must be presence of the functional group.

Explain the term $'\! Nomenclature'$ . State its need with reference to organic compounds.

The naming of organic chemistry is an important aspect in the study of organic chemistry as there number is very large and variety of molecular structures exists in their molecules. The field has become more complex on account of the phenomenon of isomerism.

Number of pi bonds in cyclic structure of ${S}_{3}{O}_{9}$ is:

From structure it can be seen that number of pi bonds are 6.

Which organic compounds are named as compounds. Alkanol in IUPAC system?

Alcohols are names as alkanols in IUPAC system. Example IUPAC name of

$CH_{3}OH$ is methanol.

Number of pi bonds in $XeO_4$ is:

Hence, answer is 4.

Find the ratio between $\pi$ bonds and lone pairs of $sp^{2-}$ hybrid orbitals in $C_3N_3(NH_2)_3$ .

3 pi bonds are present and 3 lone pairs are present in

$sp^2$ hybrid orbitals.
Hence, the ratio is

$\displaystyle\,\frac{3}{3}\,=\,1$ .
Thus, the ratio of the number of pi bonds to the number of lone pairs of electrons is

$sp^2$ hybrid orbitals is

$1:1$ .

Rules for Naming Hydrocarbons:-

Rule-I Selection of the longest carbon chain.

Rule-II Numbering the longest chain: Longest chain is numbered starting from a terminal carbon. Numbering is done is such a way that lowest possible number is given to the side cahin or a functional group.

Rule-III Writing names of branched, saturated hydrocarbons, locants are written first in alphabetical order followed by name of parent chain.

Rule-IV Some common names are retained in

$IUPAC$ system for unsubstituted hydrocarbon only.

$4,5,5-trimethyl-2-heptyne$

Here,

$yne-$ for triple bond

$hept-$ for seven carbon atoms

$yl-$ for side chain

An example for polyfunctional compound is?

An example for poly-functional compound is 4-nitro aniline. It contains nitro group and aminio groups as functional groups. Other examples includes glycine, glucose, salicylic acid etc. A poly-functional compound has more than one functional group.

How many $p-orbitals$ are parallel to each other in the following conjugated system?

Gp- orbital is benzene

and 1 p - orbital from

$CH_2^ -$ as in conjugation

So total 7 orbitals are parallel.

What is Poling process?

Poling is a method used to purify metals that have oxidized impurities. It is typically used to purify metals like copper or tin that are in the impure form of a copper oxide or tin oxide.

Rule-I Selection of the longest carbon chain.

Rule-II Numbering the longest chain: Longest chain is numbered starting from a terminal carbon. Numbering is done in such a way that the lowest possible number is given to the side chain or a functional group.

Rule-III Writing names of branched, saturated hydrocarbons, locants are written first in alphabetical order followed by name of parent chain.

Rule-IV Some common names are retained in $IUPAC$ system for unsubstituted hydrocarbon only.

IUPAC name of the following.

Hint: Alcohols are named by replacing the suffix -ane with -anol. If there is more than one hydroxyl group (-OH), the suffix is expanded to include a prefix that indicates the number of hydroxyl groups present (-anediol, -anetriol, etc.).

Explanation:

1. Identify the longest carbon chain. This chain is called the parent chain.

2. Identify all of the substituents.

3. Number the carbons of the parent chain from the end that gives the substituents the lowest numbers.

For a cycloalkane, the ring supplies the root name and the substituent group is named as usual.

So the naming of this compound is

$cyclohexan-1,4-diol$ .

What is the importance of separation of substances ? Explain.

$$\textbf {Necessity for separation of substances}$$ : The existence of any substance in its pure form is necessary. There are many substance which cannot be used due to presence of impurities in them. Therefore, to obtain a substance in its pure form separation is necessary. By separating impurities, we can increase quality, purity, strength and utility. At the same time, ratio of components of mixture can be estimated.

For example , due to presence of impurities , strength of cement decreases.
Lustre of gold decreases due to impurities .
Impure water can cause diseases .

Hence , we can say that it is very necessary to separate components of mixture.

Identify the nucleophilicity order in the following $H{ O }^{ \ominus }$ ${CH}_{3}CO{ O }^{ \ominus }$ in protic solvent:

$CH_3COO^{-}$ is more nucleophilic than

$OH^{-}$ .

In a protic solvent, an ion like

$OH^{-}$ is surrounded by a tight shell of solvent molecules. This hinders its ability to attack the substrate, so its nucleophilicity decreases. A highly electronegative atom is a poor nucleophile because it is unwilling to share its electrons.

The charge density on each oxygen atom is decreased, so acetate ion is not a strong nucleophile.

Give any four functional groups containing oxygen as the heteroatom in it. Write name and structural formula of one example each.

How will you detect the presence of carbon and hydrogen in an organic compound ?

Carbon and hydrogen in an organic compound are detected as
$CaCO_3,\ CuSO_4.5H_2O$
The organic compound is heated with dry copper oxide when $C$ and $H$ of the organic compound are oxidized to carbon dioxide and water.
Carbon dioxide is detected by passing it through lime to form calcium carbonate and the presence of hydrogen is detected by passing it through anhydrous copper sulphate (white) which turns blue (hydrated copper sulphate).

Carbon and hydrogen are detected by heating the organic compound with cupric oxide ( $CuO$ ) strongly, where carbon is oxidized to carbon dioxide and hydrogen to water. Carbon dioxide is tested by lime water test, whereas water is tested by anhydrous copper sulphate test.

Reaction:

$C+2CuO\rightarrow CO+2Cu$

$2H+CuO\rightarrow H_2O+Cu$

$CO_2+Ca(OH)_3\rightarrow CaCO_3+H_2O$

$5H_2O+CuSO_4\rightarrow CuSO_4.5H_2O$
