Question

Which of the following is/are example(s) of hydrogen bonded molecular solids?

• A. $H_2\left(s\right)$
• B. $H_{2}O\left(s\right)$
• C. $S{O}_2\left(s\right)$
• D. $H_{3}B{O}_3\left(s\right)$

Answer 1

Answer: (B), (D)

$H_{3}B{O}_3\left(s\right)$

$H_2\left(s\right)$ is a non polar molecular solid.
$S{O}_2\left(s\right)$ is a polar molecular solid.

Hydrogen Bonded Molecular Solids:

The molecules contain polar covalent bonds between H and F/O/N atoms.Strong hydrogen bonding binds molecules of such solids like $H_{2}O\left(ice\right)$.
They are non-conductors of electricity. Generally they are
volatile liquids or soft solids under room temperature and pressure.

$H_{3}B{O}_3\left(s\right)$ :


$H_{2}O\left(s\right)$:
