Dear student,
 

Polar  Covalent - Polar covalent bonds are intermediate to ionic and covalent  bonds. Polar covalent bonds form between atoms of different elements and  occur when neither element has a strong enough attraction  (electronegativity) for the electrons to remove them completely from one  another (ionic), but also in which their attractions for the electrons  are not equal (covalent). The result of this is that the electrons spend  more time orbiting one atomic nucleus than the other. One atom now has a  negative charge more than 50 percent of the time, but less than 100  percent and the other atom involved has a positive charge more than 50  percent of the time, but less than 100 percent. The bond is not ionic  and not covalent, but rather polar covalent. That sounds more what water  is.

water exhibits both covalent bond as well as hydrogen bond but covalent bond is astrong bond whereas hydrogen bond is just a weak attraction.
