Diazomethane, CH2N2, is used in the organic chemistry laboratory despite its danger because it produces very high yields and is selective for reaction with carboxylic acids. Draw the product of the reaction of this compound with excess diazomethane in methanol. As an aid, the structure of initial compound is provided for you in the drawing window.

This is reaction is an intermediate step formed during esterification reaction involving carboxyl groups and alcohol groups and diazomethane in presence of methanol serves as catalyst to form a carboxylate

Explanation:

Esterification reaction are reactions that occur between carboxylic groups and alcoholic groups. Excess diazomethane in presence of methanol acts as catalyst for this type of esterification reaction.

Excess diazomethane in methanol gives methyl acetate and nitrogen gas.

The first attachment shows the general reaction of carboxylic acid with diazomethane in presence of methanol while the second attachment is the mechanism of the reaction where protonation of diazomethane by carboxylic acid to form carboxylate before the carboxylate attacks the methyl group to displace nitrogen

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
