Assertion (A) : F-F bond in `F_2` molecules is weak.

Reason (R) : F Atom is small in size.

Asseration: F-F bond in F_(2) molecule is strong. Reason: F -atom is small in size.

Assertion (A): F-F bond in F_(2) melocule is weak. F atom is small in size.

Assertion (A): In F-F bond dissociation enthalpy is less. Reason (R): This is due to the presence of lone pairs of electrons.

Assertion: Among the halogens bond energy of F_(2) is minimum. Reason: Among halogens F atom is small in size.

Assertion : Bond dissociation energy of B-F bond in BF_(3) molecule is lower than C-F bond in CF_(4) molecule. Reason : Atomic size of B-atom is larger than that of C-atom.
