Current Question (ID: 8012)

Question:

The molecule among the following having the highest dipole moment is:

Options:

1. $ \text{CO}_2 $
2. $ \text{HI} $
3. $ \text{H}_2\text{O} $ (Correct)
4. $ \text{SO}_2 $

Solution:

HINT: If the molecule is symmetrical then its dipole moment is zero. Explanation: $ \text{CO}_2 $ being symmetrical has zero dipole moment. $ \text{O}=\text{C}=\text{O} $ $ \mu = 0 $ Among $ \text{HI} $, $ \text{SO}_2 $, and $ \text{H}_2\text{O} $ dipole moment is highest for $ \text{H}_2\text{O} $ as in it the central atom contains 2 lone pairs. Also, the polarity difference between $ \text{H} $ and $ \text{O} $ is more as compared to $ \text{H} $ and $ \text{S} $. $ \text{H} - \text{I} $ $ \mu = 0.38 \text{D} $ $ \text{H} - \text{O} - \text{H} $ $ \mu = 1.84 \text{D} $ $ \text{O} = \text{S} = \text{O} $ $ \mu = 1.62 \text{D} $
