Assertion : `F_2` has low reactivity.
Reason: F-F bond has low bond dissociation enthalpy.

F_2 has lower bond dissociation enthalpy than Cl_2 . Why?

In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. (a) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion. (b) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion. (c) Assertion is correct, but reason is wrong statement. (d) Assertion is wrong but reason is correct statement. (e) Both assertion and reason are wrong statements. Assertion : N_2 is less reactive than P_4 . Reason : Nitrogen has more electron gain enthalpy than phosphorus.

In a period from Li to F ionisation enthalpy

Assertion : P_4 is more reactive than N_2 . Reason: P-P single bond in P_4 is much weaker than N-=N in N_2 molecule.

Affinity for hydrogen decreases in the group from fluorine to iodine. Which of the halogen acids should have highest bond dissociation enthalpy?

Arrange the following in the order of property indicated for each set: F_2, Cl_2, Br_2, I_2 - increasing bond dissociation enthalpy.

Assertion : F-F bond in F_2 molecule is strong. Reason: F atom is small in size.
