Question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : $NH_{3}$ and $NF_{3}$ molecule have pyramidal shape with a lone pair of electrons on nitrogen atom. The resultant dipole moment of $NH_{3}$ is greater than that of $NF_{3}$ . Reason (R) : In $NH_{3}$ , 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 :

Options:

Answer:

A

Solution:

Resultant dipole moment $= 0.80 \times 1 0^{- 30} Cm$
Resultant dipole moment $= 4.90 \times 1 0^{- 30} cm$
