Given below are two statements: Statement I : Both NH ₃ and NF ₃ possess a trigonal pyramidal geometry. Statement II : The bond angle in NH ₃ is smaller than the bond angle in NF ₃ . In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

In both NH ₃ and NF ₃ , the central nitrogen atom is sp^3 hybridized and possesses one lone pair of electrons. According to VSEPR theory, this results in a trigonal pyramidal geometry for both molecules. Thus, Statement I is correct. In NF ₃ , fluorine is more electronegative than nitrogen, which shifts the bond pair electron density away from the central nitrogen atom. This decreases the bond pair-bond pair repulsion compared to NH ₃ , where nitrogen is more electronegative than hydrogen. Consequently, the bond an
