Current Question (ID: 8009)

Question:

A molecule among the following with non-zero dipole moment is:

Options:

1. $\text{C}_6 \text{Cl}_6$
2. $\text{C}_2 \text{Cl}_6$
3. $\text{C}(\text{CCl}_3)_4$
4. $: \text{CCl}_2$ (Correct)

Solution:

$\text{HINT: Symmetrical molecules have zero dipole moment.} \text{Explanation:} \text{Step 1:} $\text{C}_6 \text{Cl}_6$, $\text{C}_2 \text{Cl}_6$, and $\text{C}(\text{CCl}_3)_4$ \text{ all are symmetrical molecules, hence, its dipole moment is zero.} \text{Step 2:} \text{The dipole moment of } $: \text{CCl}_2$ \text{ is non-zero due to the bent shape.}
