Which of the following compounds contain(s) no covalent bonds? $$KCl,\, PH_3, \, O_2,\, B_2H_6, \,H_2SO_4$$

A$$KCl$$
Correct Answer
B$$KCl, \, B_2H_6$$
C$$KCl,\, B_2H_6,\, PH_3$$
D$$KCl,\, H_2SO_4$$

Solution

Covalent bond is formed between two nonmetals and Ionic bond is formed between one metal and one nonmetal.
So, in $$KCl$$, $$K$$ is metal and $$Cl$$ is nonmetal. Hence, It is an ionic bond it which have any covalent bond.
