Question

The ground state electronic configuration of $CO$ molecule is:

• A. $1{\sigma }^2{2\sigma }^{2}1{\pi }^{4}3{\sigma }^2$
• B. $1{\sigma }^{2}2{\sigma }^{2}3{\sigma }^{2}1{\pi }^{2}2{\pi }^2$
• C. $1{\sigma }^{2}2{\sigma }^{2}1{\pi }^{2}3{\sigma }^{2}2{\pi }^2$
• D. $1{\sigma }^{2}1{\pi }^{4}2{\sigma }^{2}3{\sigma }^2$

Answer 1

The correct option is A $1{\sigma }^2{2\sigma }^{2}1{\pi }^{4}3{\sigma }^2$

From the above image, it is concluded that- the ground state electronic configuration of $CO$ molecule is:

$1{\sigma }^2{2\sigma }^{2}1{\pi }^{4}3{\sigma }^2$

Hence, the correct option is $A$.
