Interpretation:
The product formed when Propanal reacts with Methanol.
Concept Introduction:
Hemiacetal is a type of molecule which contains carbon bonded to one -OH group and one -OR group. It is basically a half acetal. A hemiacetal forms when one molecule of alcohol reacts with a carbonyl group of an

Metformin was introduced into clinical practice in the United States in 1995 for the treatment of type 2 diabetes. More than 25 million prescriptions for this drug were written in 2000, making it the most commonly prescribed brand-name diabetes medication in the nation.

Explain the basis for your ranking.arrow_forward17-35 Suppose that you take a bottle of benzaldehyde (a liquid, bp 179°C) from a shelf and find a white solid in the bottom of the bottle. The solid turns litmus red; that is, it is acidic. Yet aldehydes are neutral compounds. How can you explain these observations?arrow_forward
