1.	Explain : Hydrogen Bond
Answer» The force of attraction existing between hydrogen atom which is attached to highly electronegative atom in a covalent molecule and more electronegative atom of another covalent molecule is called hydrogen bonding.Hydrogen bond is possible mostly in polar covalent molecules where partial charge separation is there.As this bond existed between partial charges, it is considered to be weak bond than ionic and covalent bonds.Ex: Hydrogen bond present in HF molecule.
