Question

the point group of square planar ab4 type molecules is​

Answer 1

he was so happy OK OK OK OK OK OK OK OK

Answer 2

The point group of square planar $AB_{4}$ type molecule is $D_{4h}$

Explanation:

• Square planar is the $sp_{3}d_{2}$ geometry form four pair of bond and having two Lone Pair.

• It shows $AB_{4}$ molecule type.

• $AB_{4}$ molecule with square planar geometry possess $D_{4h}$ point group

• Point group describe the Symmetry of molecule.
• Symmetry Element are line, point upon which symmetry operation performed.
• Symmetry operation are performed on the object  to leave the object indistinguishable from another
• Symmetry Operation are Identity, Proper n fold axis , Improper axis of rotation, centre of symmetry etc
