Important Topics for MS Chauhan Organic Chemistry Solutions Chapter 7 Aldehyde & Ketones

Aldehydes and Ketones

Aldehydes and ketones integrate a carbonyl functional group, C=O. These are organic mixtures with structures -CHO and RC(=O)R’ where R and R’ signify carbon-containing substituents correspondingly.

Aldehydes: In aldehydes, the carbonyl group consists of one hydrogen atom that is attached to it together with either a second hydrogen atom or a hydrogen group which may be an alkyl group or one consisting of a benzene ring.

Ketones: In ketones, the carbonyl group consists of two hydrocarbon groups that are attached to it. These can be either the ones consisting of benzene rings or alkyl groups. Ketone does not have a hydrogen atom connected to the carbonyl group.

Aldehydes and Ketones are generally known as methanol or formyl group. The carbon atom of this group has two continuing bonds that might be engaged by aryl or alkyl or its constituents. If neither of these constituents is hydrogen, the compound is a Ketone. If at least one constituent is hydrogen, the compound is considered to be an Aldehyde.

Uses of Aldehydes

  • Formaldehyde is known as a gas. It consists of 40% solutions in water, it generates Formalin which is used in conserving biological specimens.
  • Acetaldehyde is mainly used for the creation of acetic acid and pyridine derivatives.
  • Formaldehyde is used in preserving, toasting, making glues and polymeric products, as disinfectants, pesticides, and fungicides for plants. It is also used in the testing of drugs and photography.
  • Benzaldehyde is used in cosmetic products, perfumes, and dyes. It is added to offer almond flavour to food products and also used as a bee repellent.
  • When they are reacted with phenol, formaldehyde produces Bakelite, which is further used in coatings, plastics, and adhesives.

Uses of Ketones

  • Acetone is a type of ketone that is generally available and is considered as an amazing solvent used for a number of plastics and synthetic fibres.
  • Acetone is used as a nail paint remover and paint thinner.
  • Acetone is used in chemical shedding and for acne treatments.
  • Methyl ethyl ketone, chemically butanone, is a usual solvent. It is used in the creation of textiles, varnishes, paint remover, plastics, paraffin wax, etc.
  • Methyl ethyl ketone is also used as a welding negotiator for plastics due to its liquefying properties.
  • Cyclohexanone is another significant ketone which is mainly used in the creation of nylon.

Preparation of Ketones

Ketones are prepared by reacting to secondary alcohols with the hydration of alkynes. They can also be prepared by oxidizing acyl chloride with dialkyl cadmium. Both ketones and aldehydes can also be prepared by ozonolysis of alkenes.

Nomenclature of Aldehydes

  • As per the IUPAC system of nomenclature, -al is connected as a suffix to parent alkane for the identification of aldehydes. For example, H2C=O is termed as methanol which is usually called formaldehyde.
  • The group of aldehyde is always connected at the end of the primary carbon chain, and therefore the first position in the numbering is always allocated to it. It is not always essential to contain numbering in the naming.
  • Instead of IUPAC names, aldehydes and ketones are also known by their usual names. For aldehydes and ketones, the names are initiated in Greek and Latin terms. Greek letters such as α, β, etc. are used for the position of the constituents in the carbon chain.
  • The α-carbon is directly connected to the aldehyde group, β-carbon is connected to the carbon adjacent to the aldehyde group, and so on.
