Glycols add to carbonyl compunds to form acetals and ketals. The reaction is given as
Which of the following acts as a catalyst in the reaction?
dry HCl
aqueous HCl
dil
aqueous
The addition of a glycol to carbonyl compund is reversible. The equilibrium can be shifted to the right hand side by dry HCl while addition of any aqueous acid will shift at towards the left.
