Assertion : Methylene has sextet of electrons around carbon but bears no formal charge. Reason : Methylene behaves as a nucleophile.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Methylene: \(\mathrm{CH}_{2}\) behaves as an electrophile since it needs two more electrons to complete its octet.Thus option (3) is correct.

Assertion : Tertiary carbonium ions are generally formed more easily than primary carbonium ions. Reason : Hyperconjugation as well as inductive effect due to additional alkyl groups stabilize tertiary carbonium ions.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Tertiary carbonium ions are generally formed more easily than primary carbonium ions. The reason is also true; hyperconjugation and inductive effects due to additional alkyl groups stabilize tertiary carbonium ions, making them more favorable in terms of stability and formation. So, the option (1) is correct.

A teriary butyl carbocation is more stable than a secondary butyl carbocation because of which of the following ?
1 \(+\mathrm{R}\) effect of \(-\mathrm{CH}_{3}\) groups
2 \({\rm{ - R}}\) effect of \({\rm{ - C}}{{\rm{H}}_{\rm{3}}}\) groups
3 Hyperconjugation
4 \({\rm{ - I}}\) effect of \({\rm{ - C}}{{\rm{H}}_{\rm{3}}}\) groups
