Statements about Hyperconjugation:
Statement-I: Hyperconjugation is permanent effect. Statement-II: Hyperconjugation in ethyl cation involves overlapping of C(sp²)-H(1s) bond with empty 2p orbital.
- a
Statement-I incorrect but Statement-II true
- b✓
Statement-I correct but Statement-II false
- c
Both statement-I and statement-II are false
- d
Both statement-I and statement-II are true
Statement-I correct but Statement-II false
Statement I: Hyperconjugation is a permanent effect that stabilizes carbocations, radicals, and alkenes. (True)
Statement II: In the ethyl cation (), stabilization occurs via the overlap of the filled -orbital () with the adjacent empty orbital of the cationic carbon (). The statement mentions bond, which is incorrect (it's for the methyl group). Thus, Statement II is false.
