Which of the following statement is correct about the mechanism of hemiacetal and acetal formation? A. In the hemiacetal formation mechanism, the oxygen on the alcohol uses its lone pair to "attack the carbonyl carbon before the protonation of the carbonyl oxygen B. The carbocation formation is not favored during the hemiacetal formation mechanism, this is why hemiacetal are generally unstable and very reactive C. In the acetal formation mechanism, hydrolysis of water to the hemiacetal carbon center occurs as...
