Question

How many sp2 and sp3 hybridized carbons are in naproxen?

Answer 1

There are eleven `sp^2` and three `sp^3` hybridized carbons in Naproxen.

Explanation:

The structure of Naproxen is

Every double-bonded carbon atom is `sp^2` hybridized.

That includes the ten carbon atoms in the naphthalene rings and the carbonyl carbon in the carboxylic acid (11 carbon atoms).

The two methyl groups and the carbon atom attached to the ring are `sp^3` hybridized (3 carbon atoms)
