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...

Question 6 An example of a postzygotic isolating mechanism between closely related species would be which of the following? One species flowers in April, the other in August. The two species are pollinated by different species of bees. A zygote produced by syngamy of sperm and egg of the two species contains an uneven number of chromosomes. The pollen from one species will not germinate on the stigma of the other. One species is terrestrial, the other totally aquatic.
