MCQ
Among the following compounds identify the compound that has all three bonds (ionic, covalent and coordinate bond).
  • A
    Ammonia
  • ✓
    Ammonium chloride
  • C
    Sodium hydroxide
  • D
    Calcium chloride
✓

Answer

Correct option: B.
Ammonium chloride
(b) Ammonium chloride
Explanation : Ionic Bond: Ammonium chloride contains both positively charged ions $\left( NH _4^{+}\right)$and negatively charged ions $\left( Cl ^{-}\right)$held together by ionic bonds. Within the ammonium ion $\left( NH _4^{+}\right)$, there are covalent bonds between the nitrogen atom $( N )$ and the four hydrogen atoms ( H ) which involve the sharing of electrons between them. A coordinate bond, also known as a dative bond, is a type of covalent bond in which both electrons in the bond come from one atom. In the case of ammonium chloride ( $NH _4 Cl$ ), the nitrogen atom ( N ) in the ammonium ion donates a lone pair of electrons to the chlorine atom $\left( Cl ^{-}\right)$to form a coordinate bond between them. So, ammonium chloride $\left( NH _4 Cl \right)$ exhibits all three types of bonds: ionic, covalent, and coordinate bond.
