●Polar solvents have large dipole moments (aka “partial charges”); they contain bonds between atoms with very different electronegativities, such as oxygen and hydrogen.
●The greater the electronegativity difference, the more ionic the bond is. Bonds that are partly ionic are called polar covalent bonds electronegativities of the two atoms are equal.

Polar solvents are those whose molecules have a net dipole moment (not equal to zero) they dissolve polar solutes hence the origin of the phrase “like dissolves like”.
Examples are water, alcohol, acetone etc.
POLAR COVELENT
When a covalent bond is formed between heteronuclear molecules such as in HCl, the shared pair of electrons gets displaced towards the atom which is more electronegative. As a result, one end becomes slightly positively charged while the other end becomes slightly negatively charged.
These type of bonds are called polar covalent bonds and the molecules are known as polar covalent molecules.
Some other examples of polar molecules : H2O, NH3, SO2 etc
