Step-by-step solution

Identify common aldehydes and ketones

To begin, let's first identify a few well-known aldehydes and ketones. Some common aldehydes include formaldehyde, acetaldehyde, and benzaldehyde. Common ketones include acetone, ethyl methyl ketone, and cyclohexanone.

Discuss commercial uses of formaldehyde

Formaldehyde (CH2O) is a significant aldehyde with various commercial uses. It is commonly used as a disinfectant and preservative. In the manufacturing industry, it is used as a key ingredient in the production of resins, such as urea-formaldehyde and phenol-formaldehyde resins. These resins are widely applied in making wood products, particleboard, and insulation materials. Additionally, formaldehyde is used in the textile industry for fabric treatments and in the production of adhesives and glues.

Discuss commercial uses of acetaldehyde

Acetaldehyde (CH3CHO) is another important aldehyde with multiple commercial applications. It is used as an intermediate in the synthesis of various chemicals such as acetic acid, ethyl acetate, and vinyl acetate. Acetaldehyde is also used in the production of perfumes and as a flavoring agent in the food industry. Moreover, it is employed in the production of dyes, polyester resins, and fungicides.

Discuss commercial uses of benzaldehyde

Benzaldehyde (C6H5CHO) has its commercial uses mainly in the fragrance and flavoring industry. It is widely used to create almond and other fruit flavors in various food products, as well as a component in perfumes and fragrances. Additionally, benzaldehyde can serve as an intermediate in the manufacturing of pharmaceuticals and dyes.

Discuss commercial uses of acetone

Acetone (CH3COCH3) is a widely-used ketone with a myriad of commercial applications. Its primary use is as a solvent in various industrial processes, including cleaning, degreasing, and extracting pure substances. Acetone is also an essential ingredient in nail polish remover, paint thinner, and other household products. Enormous quantities are used in the production of polymers such as polycarbonate and acrylic plastic. Furthermore, it serves as an intermediate in the pharmaceutical industry for making various medicines.

Discuss commercial uses of ethyl methyl ketone

Ethyl methyl ketone, also known as methyl ethyl ketone or 2-butanone (CH3C(O)CH2CH3), is another commonly used ketone. Its primary uses include that of a solvent in paints, varnishes, lacquers, and adhesives. It is also used in the production of textiles, plastics, and rubber products. In addition, ethyl methyl ketone acts as an intermediate in the synthesis of pharmaceuticals and agrichemicals.

Discuss commercial uses of cyclohexanone

Cyclohexanone (C6H10O) is a common ketone found in industry, primarily used as a precursor in the synthesis of nylon, a popular and versatile synthetic polymer. It also acts as a solvent for various resins, such as those used in producing paints, coatings, and adhesives. Additionally, cyclohexanone is used in the production of various pharmaceuticals and insecticides.
