Hybridisation of the underlined carbon in the given species \({\rm{C}}{{\rm{H}}_{\rm{3}}}{\rm{ - C}}{{\rm{H}}_{\rm{2}}}{\rm{ - }}\underline {\rm{C}} {\rm{H}}_{\rm{2}}^{\rm{ - }}\) is
1 \({\rm{s}}{{\rm{p}}^{\rm{2}}}\)
2 \({\rm{s}}{{\rm{p}}^{\rm{3}}}\)
3 \(\mathrm{sp}\)
4 No hybridisation
Explanation:
In the given species, for underlined carbon b.p \({\rm{ = 3,1 }}{\rm{. p = 1}}\). Thus \({\rm{n = 4,i}}{\rm{.e}}{\rm{. s}}{{\rm{p}}^{\rm{3}}}\).

Assertion : Greater the \({\text{s}}\) -character of the hybrid orbital, the smaller is its size. Reason : \(\mathrm{sp}^{3}\) orbital forms the longest and \({\text{sp}}\) orbital forms the shortest bond.
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:
The \({\text{s}}\)-orbitals are closer to the nucleus than the \({\text{p}}\)-orbitals. Thus, greater the \({\text{s}}\)-character of the hybrid orbital, the smaller is its size.Therefore, the order of the size of the three hybrid orbitals is \(\mathrm{sp}^{3}>\mathrm{sp}^{2}>\mathrm{sp}\).Accordingly, \(\mathrm{sp}\) orbital forms shortest and \(\mathrm{sp}^{3}\) orbital forms longest bonds with other atoms. So, the option (2) is correct.

Assertion : Each carbon in ethylene molecule is \(\mathrm{sp}^{2}\) hybridised. Reason : The \(\mathrm{H}-\mathrm{C}-\mathrm{H}\) bond angle in ethylene molecule is \(120^{\circ}\).
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:
Each carbon in an ethylene molecule is \(\mathrm{sp}^{2}\) hybridized. The reason is also true, as the \(\mathrm{H}-\mathrm{C}-\mathrm{H}\) bond angle in ethylene is indeed \(120^{\circ}\), characteristic of \(\mathrm{sp}^{2}\) hybridization. But it is not the correct explanation. So, the option (2) is correct.
