The molecular formula of BHA is ${\text{C}}_{\text{11}}{\text{H}}_{\text{16}}{\text{O}}_{\text{2}}$ in which 11 carbon atom,16 hydrogen atom and 2 oxygen atoms are there. It is mainly used as food preservative. It acts as an antioxidant.

For example, BHA is an antioxidant. So, it can’t be oxidized or reduced.
