Explain mesomeric and inductive effects present in vinyl chloride.

Explanation

The resonace structures of vinyl chloride are:

The inductive and mesomeric effects, when present together, may act in the same direction or oppose each other. The mesomeric effect is more powerful than inductive effect. In vinyl chloride, chlorine atom should develop a negative charge due to `-I` effect but on account of mesomeric effect, it has positive charge.
