`ppi-dpi` bonding occurs between oxygen and :

p pi -d pi back bonding occurs between oxygen and

Explain the following "The ppi-ppi back bonding occurs in the halides of boron and not in those of aluminium".

The molecule in which an atom is associated with more than 8 electrons is known as hypervalent molecule and less than 8 electrons is known as hypovalent molecule. All hypervalent molecules must have ppi-dpi bonding but the molecules having back bonding back boding need not to have always ppi-dpi bondin. Q.Which of the following molecule is not having ppi-dpi bonding:

The molecule in which an atom is associated with more than 8 electrons is known as hypervalent molecule and less than 8 electrons is known as hypovalent molecule. All hypervalent molecules must have ppi-dpi bonding but the molecules having back bonding back boding need not to have always ppi-dpi bondin. Q.Which of the following molecule is not having ppi-dpi bonding:

The molecule in which an atom is associated with more than 8 electrons is known as hypervalent molecule and less than 8 electrons is known as hypovalent molecule. All hypervalent molecules must have ppi-dpi bonding but the molecules having back bonding back boding need not to have always ppi-dpi bondin. Q.Which of the molecule is not hypovalent but complete its octet:
