Updated On: Jun 7, 2024
- methyl ethyl ketone
- dimethyl ketone
- diethyl ketone
- propyi ketone
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The structure of 2-butanone is: $ C{{H}_{3}}-\overset{\begin{smallmatrix} O \\ |\,| \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{2}}-C{{H}_{3}} $ Hence, it is methyl ethyl ketone

Uses of Aldehydes and Ketones
Uses of Aldehydes:
- Formaldehyde is a gas. With 40% solution in water, it forms Formalin which is used in preserving biological specimens.
- Formaldehyde is used in embalming, tanning, preparing glues and polymeric products, as germicides, insecticides, and fungicides for plants. It is also used in drug testing and photography.
- When reacted with phenol, formaldehyde forms Bakelite, which is used in plastics, coatings, and adhesives.
- Acetaldehyde is largely used for the production of acetic acid and pyridine derivatives.
- Benzaldehyde is used in perfumes, cosmetic products, and dyes. It is added to provide almond flavor to food products and also used as a bee repellent.
Uses of Ketones:
- The most common ketone is acetone which is an excellent solvent for a number of plastics and synthetic fibers.
- In the household, acetone is used as a nail paint remover and paint thinner.
- In medicine, it is used in chemical peeling and for acne treatments.
- Methyl ethyl ketone (MEK), chemically butanone, is a common solvent. It is used in the production of textiles, varnishes, plastics, paint remover, paraffin wax, etc.
- MEK is also used as a welding agent for plastics due to its dissolving properties.
- Cyclohexanone is another important ketone which is primarily used in the production of nylon.
