Question

How many bonds does chlorine make with oxygen in perchloric acid?

• A. 3 double bonds and a single bond
• B. 7 single bonds
• C. 2 single bonds and 2 double bonds
• D. 3 single bonds and a double bond

Answer 1

The correct option is A 3 double bonds and a single bond

The formula for perchloric acid is $HOCl{O}_3$, in which the chlorine group is attached to 3 oxygen atoms and a hydroxyl group. The 3 oxygen atoms are attached to chlorine through a double bond and the hydroxyl group is singly bonded to chlorine. Thus, there are 3 double bonds and a single bond between oxygen and chlorine.
