Question: 1 / 400

How soluble is methyl carbonate (C2H3O2)?

Insoluble

Soluble in water

Methyl carbonate (C2H3O2), also known as methyl ester of carbonic acid, exhibits notable solubility in water due to its polar nature. The compound contains an ester functional group, which facilitates interactions with water molecules. The presence of the carbonyl (C=O) and the ether-like (C-O) groups contributes to its ability to form hydrogen bonds with water, enhancing its solubility.

Comparatively, many organic molecules that are completely non-polar or lack functional groups that can interact with water tend to be insoluble or only partially soluble. Given methyl carbonate's structural features, it does not fall into these categories, allowing for a strong interaction with water molecules.

While it is indeed soluble in organic solvents due to its organic structure, the most accurate characterization regarding its behavior in water is that it is soluble in water, making the selection of this choice true.
