Solution: Ethyl acetate, C4H8O2, is a fragrant substance used both as a solvent and as an aroma enhancer. Its Lewis structure is .How many valence electrons remain in nonbonding pairs in the molecule?

Problem

Ethyl acetate, C4H8O2, is a fragrant substance used both as a solvent and as an aroma enhancer. Its Lewis structure is C is single bonded above, left, and below to H, and right to C.  That C is double bonded above to O (which has two pairs of dots) and single bonded right to O.  That O has two pairs of dots and is single bonded right to C, which is single bonded above and below to H and right to CH3. .

How many valence electrons remain in nonbonding pairs in the molecule?
