Question

All of the following molecules have covalent bonds except :

• A. $HCl$
• B. $CC{l}_4$
• C. $H_{2}O$
• D. $CsF$
• E. $C{O}_2$

Answer 1

The correct option is D $CsF$

All of the following molecules have covalent bonds except caesium fluoride, CsF, which is ionic in nature.

It contains $C{s}^{+}$ and $F^{-}$ ions.

These ions are held together by strong electrostatic forces of attraction which correspond to ionic bond.

Hence option D is correct.
