Definitions :
Polarity - charge on the compound.
Lone pair — A pair of valence electrons not shared with another atom and is sometimes called non bonding pair.
Bond angle — Angle formed between three atoms across at least two bonds.
Bond angle for :
AlCl₃ = 116°
Polarity = 0
NH₂ = 104.5°
Polarity = - 1
