Question

Arrange in increasing order as indicated:
(a) H2O, NH3, H2S, HF (Polar Character)
​

Answer 1

Answer:

H2S > NH3 > H2O > HF

The bond between two unlike atoms, which differ in their affinities for electrons is said to be a polar covalent bond. This causes the covalent bond between H and Cl to have an appreciable ionic character. The compounds having polar bonds are termed polar compounds.
