Answer these two questions with explanation: (10 pts) 1. When an aldehyde or ketone is treated with diol such as ethylene glycol (1,2-ethanediol) and an acid catalyst, a cyclic acetal is formed. Draw the structure of the product you would obtain from benzaldehyde and ethylene glycol. 2. Would you expect hemiacetals to be stable in basic solutions? Explain your answer (Hint: examine the mechanism of formation of hemiacetals)
