@ghazi

ghazi · Answer

the one in which bond pair lone pair repulsion is largest

anonymous · Answer

it means..which have more no of lone pairs

ghazi · Answer

see all are from group 15 and all have equal number of lone pair so one more hint now size matters:)

anonymous · Answer

So..the one which have less size...

ghazi · Answer

yes so i guess it will be N and remember there is an exception As has smaller size as it was expected

anonymous · Answer

but the answer is  SbCl3

anonymous · Answer

Antimony which have large size

anonymous · Answer

Electro -ve matter here

ghazi · Answer

see if it has largest size it it will repel the most (lone pair to bond pair) so bond pair and bond pair will contract more makin smaller bond angles .....secondly in case of nitrogen due to smaller size effect of lone pair  will make a lesser impact...

Back - Bonding..

ghazi · Answer

no electronegativity matters only when polarity or hydrogen bonding is concerned

anonymous · Answer

There u have a point.....thxxxxx
