In which cases do you expect deviations from the idealized bond angle? check all that apply. check all that apply. pf3 sbr2 cocl2 ch4?

S Br2 must be 104.5 as in H2O but meanwhile the Br atoms have electrons from place to place them they will deter each other more than the H atoms in H2O so the bond angle will be over and above 104.5 
P F3 must be 107 as in NH3 meanwhile the F atoms have electrons around them they will deter each other more than the H atoms in NH3 so the bond angle will be over and above 107.

Because a model would make the investigation easier to understand
