If AB 4 molecule is a polar molecule, a possible geometry of AB 4 is :

If

{AB}_{4}

molecule is a polar molecule, a possible geometry of

{AB}_{4}

is :

Square pyramidal
Tetrahedral
Rectangular planar
Square planar

Solution

For ${AB}_{4}$ compound possible geometry are

Square pyramidal can be polar due to lone pair moment as the bond pair moments will get cancelled out.
