Which monomer is used to synthesize $\mathrm{poly}(\mathrm{vinyl} \mathrm{acetate})$?

• A. $\mathrm{CH}{2}_2=\mathrm{CH}\mathrm{COOH}$ (acrylic acid)
• B. $\mathrm{CH}{2}_2=\mathrm{CH}-O\mathrm{COCH}{3}_3$ (vinyl acetate)
• C. $\mathrm{CH}{2}_2=\mathrm{CH}\mathrm{OH}$ (vinyl alcohol)
• D. $\mathrm{CH}{2}_2=\mathrm{CH}\mathrm{Cl}$ (vinyl chloride)

Answer: (B)

Verified step by step guidance

1. Understand that poly(vinyl acetate) is a polymer formed by the polymerization of a specific vinyl monomer containing an acetate group.
2. Identify the general structure of vinyl monomers, which have the form \(\mathrm{CH_2=CH-}R\), where \(R\) is the substituent group attached to the vinyl group.
3. Recognize that vinyl acetate has the structure \(\mathrm{CH_2=CH-OCOCH_3}\), where the acetate group (\(\mathrm{-OCOCH_3}\)) is attached to the vinyl group.
4. Compare the given monomers: acrylic acid (\(\mathrm{CH_2=CHCOOH}\)), vinyl acetate (\(\mathrm{CH_2=CH-OCOCH_3}\)), vinyl alcohol (\(\mathrm{CH_2=CHOH}\)), and vinyl chloride (\(\mathrm{CH_2=CHCl}\)), and identify which one contains the acetate group.
5. Conclude that the monomer used to synthesize poly(vinyl acetate) is vinyl acetate, \(\mathrm{CH_2=CH-OCOCH_3}\), because it contains the acetate functional group necessary for the polymer.
