Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : NH3 and NF3 molecule have pyramidal shape with a lone pair of electrons on nitrogen atom. The resultant dipole moment of NH3 is greater than that of NF3. Reason (R) : In NH3, the orbital dipole due to lone pair is in the same direction as the resultant dipole moment of the N−H bonds. F is the most electronegative element. In the light of the above statements, choose the correct answer from the options given below :
