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

A)  NaCI                                    

B)  \[NaCl{{O}_{4}}\]

C)  \[PC{{l}_{3}}\]                                 

D)  \[POC{{l}_{3}}\]

Correct Answer: B

Solution :

                 \[NaCl{{O}_{4}}\] 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.
