In each of the following question, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R). Choose the correct answer as:
Assertion (A): F—F bond in F2 molecule is weak.
Reason (R): F atom is small in size.
Answer & explanation
Correct answer: option 2
Correct Explanation: Due to small size, the lone pairs of electrons on F-atom repel the bond pair between F-atoms. Therefore, F—F bond in F2 molecule is weak.
