Chemical bonds
there are generally two types of bonds:-
1)intra{within}molecular forces
2)inter{between}molecular forces
the intramolecular forces,are forces of attraction between atoms in
a molecule i.e. the force of attraction between atoms that forms
molecules e.g. ionic and covalent bonding.
the intermolecular forces,are ones between molecules that forms substances e.g. van deer waals,dipole-dipole,hydrogen bonds
ionic bond
Covalent Bonds
Hydrogen Bonds
when H is bonded to more electronegative elements (especifically- F2,O2,N2),H carries a partial positive charge
'due to the electronegativity difference' which enable it to bond with the more electronegative element in adjacent molecule,thus H acts as a bridge between the more electronegative atoms in adjacent molecule.
H bond can be viewed as special type of permenant dipole-dipole force.
