Answer» SOLUTION :(i) Reactivity increases as the +ve charge on CARBONYL carbon increases. Since alkyl GROUPS have +I-effect, therefore, reactivity increases as the number of alkyl groups on the carbonyl carbon decreases. (ii) Reactivity increases as the number and size of alkyl groups decreases, i.e., STERIC hindrance decreases. due to combined effect of these two factors, the reactivity increases in the order. `C_(2)H_(5)COCH_(3) lt CH_(3)COCH_(3) lt CH_(3)CHO lt HCHO`. |
