JEE MAIN - Chemistry (2021 - 27th July Evening Shift - No. 4)
Given below are two statements :
Statement I : Hyperconjugation is a permanent effect.
Statement II : Hyperconjugation in ethyl cation $$\left( {C{H_3} - \mathop C\limits^ + {H_2}} \right)$$ involves the overlapping of $${C_{s{p^2}}} - {H_{1s}}$$ bond with empty 2p orbital of other carbon.
Choose the correct option :
Statement I : Hyperconjugation is a permanent effect.
Statement II : Hyperconjugation in ethyl cation $$\left( {C{H_3} - \mathop C\limits^ + {H_2}} \right)$$ involves the overlapping of $${C_{s{p^2}}} - {H_{1s}}$$ bond with empty 2p orbital of other carbon.
Choose the correct option :
Both statement I and statement II are false
Statement I is incorrect but statement II is true
Statement I is correct but statement II is false
Both statement I and statement II are true.
Explanation
Statement I : It is correct statement
Statement II : $$C{H_3} - \mathop {C{H_2}}\limits^ \oplus $$ involve $${C_{s{p^3}}} - {H_{1s}}$$ bond with empty 2p orbital hence given statement is false.
Statement II : $$C{H_3} - \mathop {C{H_2}}\limits^ \oplus $$ involve $${C_{s{p^3}}} - {H_{1s}}$$ bond with empty 2p orbital hence given statement is false.
