Question

Which of the followig pairs has higher resonance energy:
(a).
(b). `CH_(2)=CH-O-CH=CH_(2)&CH_(2)=CH-NH-CH=CH_(2)`
(c). `CH_(2)=CH-overset(Theta)(N)H&NH=CH-overset(Theta)(N)H`

Answer 1

Correct Answer - (a)I,(b)II,(c)II
(a). In `I^(st)` part-aromaticity
(b). In `II^(nd)` part-In case of nitrogen electron availability is more.
(c). Negative charge distribute on more electronegative species.
