Eyedrops for dry eyes usually contain a water-soluble polymer called poly(vinyl alcohol), which is based on the unstable organic molecule vinyl alcohol that has the formula of C2H4O. Draw the lewis structure and predict the approximate bond angle around O 

           H    H

H - O - C = C - H

*electron pairs not shown*

Angle for O: 109.5 due to being tetrahedral

1. 4 bonding domains and no nonbonding domains

2. 2 bonding domains and 2 nonbonding domains

1. EG: tetrahedral MG: tetrahedral

2. EG: tetrahedral MG: bent
