Question

Which of the following compounds of carbon does not consist of ions?

विकल्प

• CHCl₃

• CaCO₃

• NaHCO₃

• Ca₂C

Answer 1

CHCl₃ 

Explanation:

By sharing electrons with other atoms, carbon always creates covalent compounds. Now, unlike ionic bonding, the two electrons shared by the atoms are attracted to the nucleus of both atoms in covalent bonding, and neither atom loses or obtains electrons completely. As a result, molecules with all atoms directly connected to the C-atom have covalent bonding but no ionic binding.

The three chlorine atoms in CHCl3 are all coval ently bound to the carbon atom, not to the hydrogen atom. As a result, CHCl3 is a covalent molecule with no ions.
