Chemistry
Which of the following compounds has all three bonds — ionic, covalent and coordinate bonds ?
- Ammonia
- Ammonium chloride
- Sodium hydroxide
- Calcium chloride
Answer
Ammonium chloride
Reason — When ammonium chloride NH4Cl is formed cation NH4+ (having 3 covalent and one coordinate bond) and anion Cl- are attracted towards each other, due to electrical charge existing between them and ionic bond is formed. Thus, ammonium chloride is a good example of compound having all three types of bonds i.e., covalent, coordinate and ionic bond.
