    3 compounds Those are : First one : benzaldehyde and the last one : cyclic ketone, and the seventh one : the thiophene acetal derivative. This is because only aldehydes and ketones can react with phenylhydrazine and form phenylhydrazones. Also in acidic conditions, acetal group gets removed and forms carbonyl compound. Hence total 3 compounds can form phenylhydrazone
