Which of the following statements are correct? As the s-character of a hybrid orbital decreases I) The bond angle decreases II) The bond strength increases III) The bond length increases
1 (I) and (III)
2 (II) and (III)
3 (I) and (II)
4 All are correct
Explanation:
\(\%\) s-character \(\propto\) bond angle \(\%\) s-character \(\propto\) bond order \(\%\) s-character \(\propto\) bond strength \(\%\) s-character \(\propto \dfrac{1}{\text { bond length }}\)

Which of the following molecule contain 50% p-character of hybrid orbital in C atom?
1 Acetylene
2 Methane
3 Ethane
4 propene
Explanation:
Acetylene molecule contain 50% p-character of hybrid orbital in C atom because in the hybrid orbital of acetylene both carbons are sp hybridised. An sp-orbital is composed of one s orbital and one p-orbital, and thus, it has 50% s character and 50% p-character

As the s-character of hybridised orbital increases, the bond angle
1 increases
2 decreases
3 becomes zero
4 does not change
Explanation:
Bond angle increases with increase in \(\% \mathrm{~s}^{-}\) character.

The molecule which contains \(\sigma_{\mathrm{sp}^{3}-\mathrm{sp}^{3}}\) and \(\sigma_{\mathrm{sp}^{3}-\mathrm{p}}\) bonds in it is
1 \(\mathrm{CH}_{3} \mathrm{CH}_{3}\)
2 \(\mathrm{CH}_{3} \mathrm{CHO}\)
3 \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{Cl}\)
4 \(\mathrm{CHCl}_{3}\)
