Explanation
Formaldehyde is an organic compound with the formula CH2O or HCHO. It is the simplest aldehyde, and is also called by its systematic name methanal. The common name of the substance comes from its similarity and relation to formic acid. A saturated water solution, of about 40% formaldehyde by volume or 37% by mass, is called "100% formalin".
Tollen’s reagent is a chemical reagent used to determine the presence of an aldehyde or alpha-hydroxy ketone functional groups. An aldehydes gives positive test with this reagent.
2 [Ag(NH3)2]+ + RCHO + H2O → 2 Ag(s) + 4 NH3 + RCO2H + 2 H+
Pinacolone is 3,3-dimethyl-2-butanone.
Formaldehyde reacts with NH3 to give hexamethylenetetramine
6CH2O + 4NH3 → (CH2)6 N4 + 6H2O
Among acetic acid, phenol and n-hexanol only CH3COOH reacts with NaHCO3 to evolve CO2 gas
RCONH2 + HNO2 → RCOOH + N2 + H2O
ClCH2COOH > HCOOH > CH3COOH > C2H5COOH
