Multiple choice

Directions: In the question given below, there are two statements labelled as Assertion (A) and Reason (R). Mark your answer as per the codes provided below: Assertion: NF3 has dipole moment but, BF3 has not. Reason: If the molecule is unsymmetrical, the resultant dipole moment of the molecule is not zero.

  1. Both A and R are true and R is the correct explanation of A.

  2. Both A and R are true but R is not the correct explanation of A.

  3. A is true but R is false

  4. A is false but R is true.

  5. Both A and R are false.
