Question

Consider the skeletal structure of naphthalein (C10H8), the active ingredient in mothballs. How many double bonds must be added to give each carbon atom an octet?

Answer 1

In order to obey the octet rule, we must have five double bonds in naphthalene.

Naphthalene is a polycyclic hydrocarbon. This means that is contains more than one benzene ring and is made up of only carbon and hydrogen atoms. The molecular formula of the compound is C10H8.

In order to obey the octet rule, we must have five double bonds in the molecules making a total number of five pi bonds and five sigma bonds in naphthalene.
