Explanation
– CH3 group shows +I effect and –Br, –Cl and –NO2 shows –I effect.
Due to resonance C–H bond in toulene has partial double character
Order of stability of carbocation isTriphenyl methyl > diphenyl methyl > benzyl > alkyl > 30 > 20 > 10 > methyl carbocation
There are seven isomers of C4H10 O. In which four are alcohol and three are ethers. The isomers are
Plane hexagon conformer of cyclohexane is least stable due to angle strain. So its bonds are not at 109.50. It also torsional strain
(+) and (-) tartaric acids do not possess any element of symmetry
Ethyl alcohol shows functional isomerism with dimethyl ether.
C2H5OHCH3 – O – CH3
Alcohol ether
Ethers show functional iosmerism with alcohols
Pentene-2 exhibit cis and trans isomerism
2,2-diemethy butane is a 6-carbon hydrocarbon. Rest all are the chain isomers of pentane
Tautomerism is a dynamic isomerism because two forms of substance cannot be separted, thus they are in dynamic equillibrium with each other
There are six isomers are possible for the compounds having molecular formula C4H8O
The amount of anolic form is highest in acetyl acetone due to the stabilisation of enolic form by hydrogen bonding. Amount of keto form is 24% and enol form is 76%
Racemic mixture is formed by mixing two chiral compounds
Napthalene is purified by one process of sublimotion because nepthalene sublimes on heating substances which sublimes on heating are usually purified by the process of sublimation.
O – nitrophenol is steam valatile due to intra molecular hydrogen bonding where as p – nitrophenol is less volatile due to intermolecular hydrogen bonding.
Chromatography method is used to separate sugars.
Double bond has more preference over alkyl group. So, naming is done from doubly bonded carbon of left side hence IUPAC name of given compound is 3-methyl-1-butene
A copound of carbon and hydrogen only is known as hydrocarbon. There are three types of hydrocarbon – saturated, unsaturated an anomatic
