Question

Consider the following statements.
(a)$C_2$ contains only $\pi$-bond
(b)$\pi 2p_x$ has two nodal planes
(c) Bond order of $C{O}^{+}$ is $3.5$
The correct statement(s) is/are:

• A. (a) only
• B. (a),(b) only
• C. (c) only
• D. (a),(b) and (c)

Answer 1

Answer: (C)

(c) only

Only $\Pi$ bond will not present unless a sigma bond present.

$\to$ Bond order $=\frac{No.ofbondingelectrons-No.ofanti-bondingelectrons}{2}$

$\therefore$ ${CO}^{+}=3.5$

$\to$ The correct statement above is only (C)

Ans :- Option C.
