(a)
Interpretation:
From the given pair, the more reactive ketone has to be identified.
Concept introduction:
The relative reactivity of carbonyl groups:
Carbonyl group is polar because oxygen is more electronegative than the carbon. As results carbonyl group is an electron deficient and it is an electrophile.
An
The ketones with small alkyl groups bonded to the carbonyl carbon are more reactive than those with large alkyl groups.
(b)
Interpretation:
From the given pair, the more reactive ketone has to be identified.
Concept introduction:
The relative reactivity of carbonyl groups:
Carbonyl group is polar because oxygen is more electronegative than the carbon. As results carbonyl group is an electron deficient and it is an electrophile.
An aldehyde has a greater partial positive charge on its carbonyl carbon than a ketone because an alkyl group is more electrons donating than hydrogen.
The ketones with small alkyl groups bonded to the carbonyl carbon are more reactive than those with large alkyl groups.
