Which of the following are not ionic compounds?
(i) KCl
(ii) HCl
(iii) CCl4
(iv) NaCl
(a) (i) and (ii)
(b) (ii) and (iii)
(c) (iii) and (iv)
(d) (i) and (iii)
Ans. (b)
Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.
(i) KCl: formed by the transfer of electrons and hence ionic.
(ii) HCl: polar covalent compound (formed by sharing of electrons)
(iii) CCl4: is a non-polar covalent compound (formed by sharing of electrons)
(iv) NaCl: formed by the transfer of electrons and hence ionic.
Hence (ii) and (iii) are not ionic.
Therefore option (B) is correct
