Answer:
Eight electrons are shared.
Explanation:
The total valence electrons available in the given compound are:
4 from carbon
seven each from two chlorine atoms
one each from hydrogen atom
Total = 4 +2 + 14 = 20 electrons
Out of these 20 eight will be involved in making four bonds as:
a) two separate bonds with two chlorine atoms and carbon
b) two separate bond with two hydrogen atoms and carbon
In each bond two electrons are shared.
Total electrons shared = 8.
Rest electrons will be lone electrons on chlroine atoms (six on each atom).
