How many bonds are present between oxygen and chlorine in perchloric acid?
One single bond and 3 double bonds
9 single bonds
3 single bonds and 4 double bonds
5 double bonds
If we remember the formula for perchloric acid that will be . Here as we can see chlorine is attached to three oxygen where one double bond is present for each and chlorine is also attached to the hydroxyl group through one single bond, therefore a total of 3 double bonds and one single bond are present.
