hard
Incorrect statement when $C_2$ change to $C_2^{-2}$
A
Magnetic properties remain same
B
Bond order increases
C
$\sigma $ bond decreases
D
$\pi $ bond increases
Solution
$\mathop {{C_2}}\limits_{\left( {2\,\pi \,bond} \right)} \to \mathop {C_2^{ – 2}}\limits_{\left( {2\pi + 1 – bond} \right)} $
