Solution

Solution Steps

Step 1: Examine the monomer and polymer structures

Vinyl acetate has an alkene functional group (C=C) and an ester functional group (R-COOR'). Polyvinyl acetate repeats a structure that contains an ester functional group but where the C=C has been replaced by a C-C single bond.

Step 2: Identify the lost functional group

The alkene functional group from the vinyl acetate monomer is lost when the polymer, polyvinyl acetate, is formed.
