Solution

The correct option is D

Ammonium chloride


Part 1: Explanation For the correct answer.

Option D: Ammonium Chloride (NH4Cl)

  1. It is formed when a positively charged ammonium ion (NH4+) comes in contact with the negatively charged chloride ion Cl-, forming an ionic bond.
  2. The ammonium ion is formed when a lone pair of ammonia (NH3) is shared with H+ ion forming a coordinate bond.

Part 2: Explanation of incorrect option:

Option A: Carbon tetrachloride

  1. It is formed when 4 valence electron of C is shared with the Chloride(Cl) atom forming a covalent bond.

Option B: Hydrogen (H2)

  1. The bond formed by sharing electrons of the same element is always a covalent bond.

Option C: Hydrogen Chloride (HCl)

  1. It is formed when 1 electron of His shared with the 1Chloride(Cl) atom forming a covalent bond.

So, Option D is correct. Ammonium chloride (NH4Cl) has a coordinate bond in the given compounds.
