MCQ
The percentage $s-$character of the hybrid orbitals in methane, ethene and ethyne are respectively
- ✓$25, 33, 50$
- B$25, 50, 75$
- C$50, 75, 100$
- D$10, 20, 40$
✓
Answer
Correct option: A.
$25, 33, 50$
(a) $\%$ of $s-$character in
$\mathop {C{H_4}}\limits_{(s{p^3})} = \frac{{100}}{4} = 25$,
$\mathop {{C_2}{H_4}}\limits_{(s{p^2})} = \frac{{100}}{3} = 33$,
$\mathop {{C_2}{H_2}}\limits_{(sp)} = \frac{{100}}{2} = 50$
