Question

Which of the following compounds has both ionic and covalent bonding?

• A. $NaBr$
• B. $Ba(CN{)}_2$
• C. $PC{l}_5$
• D. $C{H}_{3}C{H}_{2}OH$

Answer 1

The correct option is B $Ba(CN{)}_2$

$Ba(CN{)}_2$ consists of $B{a}^{+2}$ and 2 $C{N}^{-}$ ions. Hence, it is ionic in nature.

$C{N}^{-}$ contains a triple covalent bond between C and N. So, this compound contains both ionic and covalent compound.
