What happens when simple ketone reacts with glycols in the presence of acids like p-toluene sulphonic acid (pTs)?

Cyclic hemiketals are formed  Cyclic ketals are formed  Acids are formed  Does not react

Cyclic ketals are formed

Acid catalyzed reaction of alcohols with ketones is not as easy as with aldehydes. But, simple unhindered ketones react with alcohols preferably glycols tp form ketals in the presence of acids like p-toluene sulphonic acid (pTs).
