Question

Which of the following compounds of chlorine contains both ionic and covalent bonds?

• A. $NaCI$
• B. $NaClO_{4}$
• C. $PCl_{3}$
• D. $POCl_{3}$

Answer 1

Answer: (B)

$NaClO_{4}$

Answer 2

$NaClO _{4}$ contains both ionic and covalent bonds. $Na$ is highly electropositive and $ClO _{4}^{-}$is highly electronegative, so they will form ionic bond. Perchlorate ion, $ClO _{4}^{-}$has a tetrahedral structure with $s p^{3}$ hybridisation. $Cl$ and $O$ are bonded through covalent bonds.
