Question
Write the bond angles in $\mathrm{CH}_4, \mathrm{NH}_3$ and $\mathrm{H}_2 \mathrm{O}$ molecules and give reason.
✓
Answer
$\mathrm{CH}_4$ has bond angle $109.5^{\circ}$ because it has 4 bp and no lone pair. $\mathrm{NH}_3$ has bond angle $\because 107^{\circ}$, it has 3 bp and 1 lp .
$\mathrm{H}_2 \mathrm{O}$ has bond angle $104.59, \because$ it has 2 bp and 1 lp .
$\mathrm{H}_2 \mathrm{O}$ has bond angle $104.59, \because$ it has 2 bp and 1 lp .
