Bond pairs and lone pairs are 2 types of valence shell electron pairs.
Bond pairs are shared among 2 atoms and occupy less space and cause less repulsion, while lone pairs are not involved in bond formation, occupy more space and cause much more repulsion.
Based on the bond angles in CH4, NH3, and H2O. rank the magnitude of these repulsions. Rank from strongest to weakest repulsion. To rank items as equivalent, overlap them.
