1) The bond angles of NH3,NH+4 and NH−2 are in the order A) NH−2> NH3 > NH−4 B) NH+4 > NH3 > NH−2 C) NH3 > NH−2 > NH−4 D) NH > NH−4 > NH−2 Answer: Option BExplanation:On increases the number of lone pairs of electrons , bond angle decreases . therefore , order of bond angle is NH+4 >NH3 >NH−2 (no/p) (one/p) (two/p)
