Question

Increasing order of negative electron gain enthalpy?

a) N<O<Cl<Al b) O<N<Al<Cl

c) N<Al<O<Cl d) Cl<N<O<Al​

Answer 1

Answer:

Al is a metal so Al has lowest electron gain enthalpy.

Cl has highest electron gain enthalpy.

And electron gain enthalpy increases along a period.

∴ The correct order is Al<N<O<Cl.
