An organic compound having molecular formula `C_5H_(10)` O exists in two chain isomers, (A) and (B).Isomer (A) undergoes Cannizzaro reaction to give 2, 2- dimethyl propanoic acid 2,2- dimethyl propanol - 1. Compound (B) in the presecne of dilute alkali undergeos aldol condensation to form 3 - hydroxy -2- propyl heptanal. Give the structures of (A) and (B).

Explanation

Isomers have the formula, `C_(4)H_(9)CHO`. Isomer (A) undergoes Cannizzaro reaction, thus it does not have `alpha`-hydrogen. The structure of (A) is `(CH_(3))_(3)C CHO`.
`(CH_(3))_(3)C CHO overset(NaOH)rarr (CH_(3))_(3)C COOH+ (CH_(3))_(3)C CH_(2)OH`
Isomer (B) undergoes aldol condensation as it possesses `alpha`-hydrogen atom. The structure of (B) is `CH_(3)CH_(2)CH_(2)CH_(2)CHO`.
