Given below are two statements :
Question:

Given below are two statements :

Statement I : Hyperconjugation is a permanent effect.

Statement II : Hyperconjugation in ethyl cation

$\left(\mathrm{CH}_{3}-\stackrel{+}{\mathrm{CH}_{2}}\right)$ involves the overlapping of $\mathrm{C}_{s p^{2}}-\mathrm{H}_{1 s}$ bond with empty $2 \mathrm{p}$ orbital of other carbon.

Choose the correct option :

  1. Both statement I and statement II are false

  2. Statement I is incorrect but statement II is true

  3. Statement I is correct but statement II is fals

  4. Both Statement I and statement II are true.


Correct Option: , 3

Solution:

Statement I : It is correct statement

Statement II : $\mathrm{CH}_{3}-\mathrm{CH}_{2}$ involve $\mathrm{C}_{\mathrm{sp}^{3}}-\mathrm{H}_{1 \mathrm{~s}}$

bond with empty $2 p$ orbital hence given statement is false.
