Which of the following best represents the general name of the product formed in Experiment 2?

A Hemiacetal
B Acetal
C Ketal
D Hemiacetal
Ans. B The product that is formed in Experiment 2 is an acetal. When one mol of the given compound reacts with two moles of the alcohol, the product formed is an acetal. A simple acetal does not have the -OH group, whereas a hemiacetal has the -OH group.
