Current Question (ID: 8007)

Question:

Non-Zero dipole moment is shown by :

Options:

1. $\text{CO}_2$
2. p-Dichlorobenzene
3. Carbontetrachloride
4. Water. (Correct)

Solution:

$\text{HINT: Symmetrical molecules have zero dipole moment.} \text{Explanation:} \text{1.) } \text{CO}_2 \text{ is linear in shape. So, the net dipole moment of } \text{CO}_2 \text{ will be zero.} \text{O=C=O} \leftrightarrow \mu + \mu = 0 \text{2.) The dipole moment of p-dichlorobenzene will be zero.} \text{3.)Similarly, } \text{CCl}_4 \text{ will have zero dipole moment because of its perfect tetrahedral shape.} \text{4.) The dipole moment of the water molecule is non-zero because of it's angular shape.}
