MCQ
Incorrect statement when $C_2$ change to $C_2^{-2}$
- AMagnetic properties remain same
- BBond order increases
- C$\sigma $ bond decreases
- ✓$\pi $ bond increases
✓
Answer
Correct option: D.
$\pi $ bond increases
d
$\mathop {{C_2}}\limits_{\left( {2\,\pi \,bond} \right)} \to \mathop {C_2^{ - 2}}\limits_{\left( {2\pi + 1 - bond} \right)} $
$\mathop {{C_2}}\limits_{\left( {2\,\pi \,bond} \right)} \to \mathop {C_2^{ - 2}}\limits_{\left( {2\pi + 1 - bond} \right)} $
