Question

Ionic and covalent bonds are present in:
(a) $ CC{l_4} $
(b) $ CaC{l_2} $
(c) $ N{H_4}Cl $
(d) $ {H_2}O $

Answer 1

Hint: As we know that ionic bonds and covalent bonds are the two most important bonds which we apply in chemistry. Ionic bonds are stronger than covalent bonds. But one molecule here contains both bonds. The complete answer of the above question is given in the below section in brief.

Complete answer:
Here, in the given four options $ N{H_4}Cl $ is the only molecule which forms both ionic and covalent bonds. Therefore, option C is the correct option. In this molecule, an ionic bond is present or formed between $ NH_4^ + $ and $ C{l^ - } $ ions whereas the covalent bond is formed between N and three H atoms. Total of three covalent bonds are formed between them. Not only ionic and covalent bonds are present in this molecule but there is one more bond also present in this molecule and this bond is a coordinate bond. It is formed between N and one H atom. Other molecules like calcium chloride contain covalent bonds, water also contains covalent bonds and there is also covalent bond present in carbon tetrachloride molecules.

Note:
The chemical name of $ N{H_4}Cl $ is ammonium chloride. It is a white crystalline salt that is highly soluble in water. The natural, pure and mineralogical form of ammonium chloride is known as Sal ammoniac. It is formed by the reaction of hydrochloric acid and ammonia. It is mainly used as fertilizer. It’s another use as a flavoring agent in some types of liquorice.
