Given below are two statements:
Statement I : Hyperconjugation is a permanent effect.
Statement II : Hyperconjugation in ethyl cation $\displaystyle \left(\mathrm{CH}_3-\stackrel{+}{\mathrm{C}} \mathrm{H}_2\right)$ involves the overlapping of $\displaystyle \mathrm{C}_{\mathrm{sp}^2}-\mathrm{H}_{1 \mathrm{~s}}$ bond with empty $\displaystyle 2$ p orbital of other carbon.Choose the correct option :
Official answer
(3)
