Question

What is a methyl ketone $?$

Answer 1

Hint : First understand what a ketone is. When we say that a ketone is a methyl ketone. Then we understand the definition of methyl ketone and the properties.Then we know whether the given ketone is methyl ketone or not.

Complete Step By Step Answer:
A ketone is a functional group with the structure ${R_2}C = O$ , $R$ where there can be a variety of carbon-containing substitutes. It contains a carbon-oxygen double bond. acetone is an example of a ketone.
Methyl ketone is an organic compound containing a carbonyl group $(C = O)$ bound to two hydrocarbon groups. Some examples of methyl ketones are acetone, ethyl methyl ketone $\left( {C{H_3}C{H_2}COC{H_3}} \right)$ and acetophenone $\left( {{C_6}{H_5}COC{H_3}} \right)$ .
A methyl ketone is a ketone in which a methyl group is attached to the carbonyl group. It is prepared from carboxylic acids by reaction with methyllithium.
Iodoform Reaction: This test is used to check if the given ketones are methyl ketones or not. The iodoform test indicates the presence of ketone in which one of the groups directly attached to the carbonyl carbon is a methyl group. In this test, the unknown is allowed to react with a mixture of excess iodine and excess hydroxide.

Note :
Note that in a methyl ketone, at least one of the hydrocarbon groups is a methyl group. The ketones are also known as aldehydes.Methyl ethyl ketone is also known as ethyl methyl ketone and it is not soluble in water and colourless.
