Question

Choose the molecule which exhibits polar character.

• A. $H_{2}O$
• B. $C{l}_2$
• C. $O_2$
• D. $B{r}_2$

Answer 1

The correct option is A $H_{2}O$

$\bullet$ When electrons are shared between atoms of different electronegativity, the shared pair of electron gets more attracted to one atom. Due to this, partial charge develop over the atoms. These molecules exhibit polar character.

$\bullet$ For example, the water molecule is made of hydrogen and oxygen having different electronegativity. Hence, it exhibit polar characteristics.

$\bullet$ Whereas, all other molecules have atoms of same electronegativity. So, they do not exhibit any polar character.
