1.	If AB_(3) (For atom) molecule posses dipole moment zero and not zero than what is it indicate ?
Answer» Solution :If `AB_(3)` molecule, `mu` = 0, So, It should be DECIDE that its shape is symmetrical TRIANGLE. It `AB_(3)` molecule, `mu NE `So, it should be decide the its shape should be TRIGONAL PYRAMIDAL.
