Question

Choose the correct option for $C{O}_2$ molecule in view of chemical bonding.

• A. Non-linear
• B. $\mu \ne 0$
• C. Both $A$ and $B$
• D. $\mu =0$

Answer 1

The correct option is D $\mu =0$

Lewis dot structure of $C{O}_2$ molecule

(IMAGE)

$\Rightarrow O=C=O$

$\therefore$ C atom is sp hybridized and hence it is linear in shape

Due to symmetry of electron distribution around carbon atom, $C{O}_2$ molecule has dipole moment zero.

$\therefore$ Option D is correct.
