Question

Halogens don’t exhibit -1 oxidation state - True or False?

• A. True
• B. False

Answer 1

The correct option is B False

Consider a simple compound hydrogen bromide and calculate the oxidation state like
HBr 1 + X = 0, hence X = -1
Thus halogens exhibit -1 oxidation state in HCl, HF, HBr, HI. They tend to be electronegative and -1 is a very common oxidation state.
