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) undeergoes Cannizaro 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`.
`CH_(3)CH_(2)CH_(2)CH_(2)CHO + H - underset(underset(CHO)(|))(CH) - CH_(2) - CH_(2) - CH_(3) rarr CH_(3) - CH_(2) - CH_(2)- CH_(2) - underset(underset(OH)(|))(CH)- underset(underset(CHO)(|))(CH)- CH_(2) - CH_(2)-CH_(3)`
