The shape of the BH₃ molecule is trigonal planar, while NH₃ has a trigonal pyramidal shape. Choose the best statement to describe these observations.
Boron has larger atomic size than nitrogen
Boron has three valence electrons while nitrogen has five valence electrons
Nitrogen is more electronegative than boron
Boron is metalloid while nitrogen is non-metal
The bond angles in NH3 are bigger than bond angles in H2O because
all the bonding electrons in NH3 repel each other equally
the nonbonding electrons in H2O exert greater repulsive forces on bonding electrons.
oxygen is more electronegative than nitrogen and the O-H bond is more polar than N-H bond
oxygen has smaller atomic size than nitrogen.
