The molecule which has all the three characters i.e. ionic, covalent and coordinate covalent, is:
Answer: NH4Cl
Explanation
The molecule that exhibits all three types of bonding—ionic, covalent, and coordinate covalent—is NH4Cl (ammonium chloride).
Ionic Bonding:
In NH4Cl, the bond between ammonium (NH4+) and chloride (Cl-) ions is primarily ionic.
Covalent Bonding:
Within the ammonium ion (NH4+), the bonds between nitrogen and hydrogen atoms are covalent.
Coordinate Covalent Bonding:
In NH4Cl, there is also a coordinate covalent bond between the ammonia (NH3) molecule and a proton (H+) from hydrochloric acid (HCl) that forms ammonium (NH4+)
