Polar covalent compounds: unequal sharing of electrons. Basically, one element has a much higher electronegativity ("liking" of electrons) than the others. Like in water: Oxygen has a much higher electronegativity and positive charge than the hydrogens. So, the electrons will spend most of their time with the oxygen. This will make the oxygen act like a negative and the hydrogen act like a positive.
alchohols and amines are water soluble due to H-bonding with water .they are poler covalent compound there fore they are soleble in water.

the CH4 poler
Because the electronegativities values of Be and Mg are high in comparission of other elements of the group. These two metals form poler covalent bond with hydrogen and due to polarity the units of these hydrides are linked to gather in the form of chain by hydrogen bond. so thier hydrides are called polymeric hydrides.
Polar molecules are attracted to other polar molecules with an opposite charge.
