Question

Number of Cl = O bond(s) in HClO4 molecule is

Answer 1

Number of Cl=O bonds in $HClO_{4}$ molecule is 3.

Explanation:

• In a $HClO_{4}$ molecule, chlorine atom is located at the center and it has seven valence electrons. And, its surrounding atoms are oxygen which contains 6 valence electrons.

• Therefore, out of the four oxygen atoms each of the three oxygen atoms are attached to the chlorine atom with a double bond.  

• And, the fourth oxygen atom is attached to the chlorine atom through a single bond on one end and another end is attached to hydrogen atom. So, there are 3 Cl=O  bonds present in 1 molecule of $HClO_{4}$.
