Question

The compound that does not have a lone pair of electrons is ________ (water, ammonia, carbon tetrachloride)

Answer 1

Lone pair:

1. The pair of electrons in an atom that does not take part in bond formation is called lone pair of electrons.
2. ${\mathrm{H}}_2\mathrm{O}\to \mathrm{H}-\underset{\circ \circ }{\overset{\circ \circ }{O}}-\mathrm{H}$ . It has two lone pairs of electrons
3. .${\mathrm{NH}}_3\to \mathrm{H}-\underset{\underset{ }{\overset{|}{H}}}{\overset{\circ \circ }{N}}-\mathrm{H}$. It has one lone pairs of electrons
4. ${\mathrm{CCl}}_4\to \mathrm{Cl}-\underset{\underset{ }{\overset{|}{Cl}}}{\overset{\underset{|}{Cl}}{C}}-\mathrm{Cl}$. It has no lone pair of electrons

So, The compound that does not have a lone pair of electrons is Carbon tetrachloride $\mathbf{\left(}{\mathbf{CCl}}_{\mathbf{4}}\mathbf{\right)}$.
