Solution: The lactic acid molecule, CH3CH (OH) COOH, gives sour milk its unpleasant, sour taste.What are the approximate bond angles around each carbon atom in the molecule?

Problem

The lactic acid molecule, CH3CH (OH) COOH, gives sour milk its unpleasant, sour taste.

What are the approximate bond angles around each carbon atom in the molecule?

Solution

The Valence Shell Electron Pair Repulsion (VSEPR) theory gives bond angles based on the number of groups around the central element. 

The table below shows corresponding electron geometry and bond angles based on the number of electron regions (lone pairs/atoms/groups).
