JEE Main Chemistry question
In which of the following, the bond angles on the -hybridised central atom are NOT contracted due to lone pairs of electrons?
Answer: (C)
Solution
In and , the central oxygen bears two lone pairs that compress the bond angle below through lone pair–bond pair repulsion (this contraction is even stronger in , since the highly electronegative F atoms pull bonding density away from O, increasing the s-character — and hence the
