Explanation:

Carbon always forms covalent compounds by sharing its electrons with other atoms. Now, in covalent bonding, the two electrons shared by the atoms are attracted to the nucleus of both atoms and neither atom completely loses or gains electrons as in ionic bonding. So the compounds in which all the atoms are directly attached to C-atom, contain covalent bonding and no ionic bond.

In CHCl3, all the three chlorine atoms are bonded covalently to the carbon atom, not to the hydrogen atom. So CHCl3 is a covalent compound and does not consist of ions.
