Also, The total Mr of the compound is 88. After reacting with ethanol, C2H5OH, the product would be the ester in option B in the ans.

I would go for D. A and D seems to be the answer as they both have th alcohol structure. However, A do not have the molecular mass of 88. Instead, A has a molecular mass of 60. Hence, it is wrong. Hi.

A and D seems to be the answer as they both have th alcohol structure.

However, A do not have the molecular mass of 88. Instead, A has a molecular mass of 60. Hence, it is wrong.

The structural formulae adds up to a Mr of 88. And it only shows COOH func group, not an ester which is B&C My ans is D.
