An organic compound having molecular formula C_(5)H_(10)O exixts in two chain ismors. (A) and (B). Iosomer (A) undergoes the Cannizzaro's reaction to give 2,2dimethyl propanic acid and 2,2dimethyl propan-1-ol. Compound (B) in the presence of dilute alkali undergoes aldol condensation to from 3-hydroxy-2-proplheptanal. Give graphi representation of (A) and (B) |

Answer» Solution :ISOMER have formula `C_(4)H_(9)CHO`. (A) undegoes Cannizaro' reaction, thus it does not have `alpha` hydrogen. The rstructure of f(A) is `(CH_(3))_(3)C CHO` `(CH_(3))_(3)underset((A))(C)-CHOoverset(NaOH)rarrunderset(2,2-"Dinethylpropanoic acid")((CH_(3))_(3)C-COOH)+underset(2,2-"Dimethylpropan-1-ol")((CH_(3))_(3)-CH_(2)OH)` (B) undergoes ALDOL CONDENSATION, it possesses `alpha`- hydrogen atom. The structure of (B) is `CH_(3)CH_(2)CH_(2)CHO` `CH_(3)CH_(2)underset((B))(CH_(2))CH_(2)CHO+H-underset(CHO)underset(|)(CH)CH_(2)CH_(2)CH_(3)rarrCH_(3)CH_(2)CH_(2)CH_(2)underset(3-"Hydroxy-2-propylheptanal")underset(OH)underset(|)(CH)-underset(CHO)underset(|)(CHCH_(2))CH_(2)CH_(3)` |
