Question: Which of the following is an example of a ketone?

Ketones contain a carbonyl group (a carbon-oxygen double bond). The simplest ketone is acetone (R = R’ = methyl), with the formula CH3C(O)CH3. Many ketones are of great importance in industry and in biology. Examples include many sugars (ketoses), many steroids (e.g., testosterone), and the solvent acetone.

What is a ketone molecule?

Ketone, any of a class of organic compounds characterized by the presence of a carbonyl group in which the carbon atom is covalently bonded to an oxygen atom. The remaining two bonds are to other carbon atoms or hydrocarbon radicals (R):

Which of these molecules is a ketone?

Ketones are organic molecules that have a carbonyl group with the structure RC(=O)R’. … So, the only molecule that is a ketone is the molecule C. This molecule is the smallest ketone – the acetone.

How do you identify a ketone?

They are named by finding the carbonyl group and identifying it with a location number, if necessary, then adding the suffix “-one.” The common name for ketones is determined by naming the alkyl groups attached to the carbonyl (in alphabetical order), then adding ‘ketone’.

What are ketones quizlet?

Ketones. Any of a class or organic compounds containing the carbonyl group, C=O, whose carbon atom is joined to 2 other atoms; the carbonyl group occurs w/n the carbon chains. Ketone.

What are the uses of ketone?

Uses of Ketones

The most common ketone is acetone which is an excellent solvent for a number of plastics and synthetic fibres. 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.

What is the importance of ketones?

You produce them when you don’t have enough insulin in your body to turn sugar (or glucose) into energy. You need another source, so your body uses fat instead. Your liver turns this fat into ketones, a type of acid, and sends them into your bloodstream. Your muscles and other tissues can then use them for fuel.

What is the meaning of ketone?

Ketones (chemically known as ketone bodies) are byproducts of the breakdown of fatty acids. The breakdown of fat for fuel and the creation of ketones is a normal process for everyone. In a person without diabetes, insulin, glucagon, and other hormones prevent ketone levels in the blood from getting too high.

What is the functional group of ketone?

Nomenclature of Aldehydes and Ketones. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents.

Are aldehydes acidic or basic?

Because of resonance stabilization of the conjugate base, an α-hydrogen in an aldehyde (not shown in the picture above) is far more acidic, with a pKa near 17, compared to the acidity of a typical alkane (pKa about 50).

How will you distinguish between aldehyde and ketone?

You will remember that the difference between an aldehyde and a ketone is the presence of a hydrogen atom attached to the carbon-oxygen double bond in the aldehyde. Ketones don’t have that hydrogen. … Aldehydes are easily oxidized by all sorts of different oxidizing agents: ketones are not.

Which test is used to distinguish aldehydes from ketone?

Tollens Test

The Tollens’ test is a reaction that is used to distinguish aldehydes from ketones, as aldehydes are able to be oxidized into a carboxylic acid while ketones cannot. Tollens’ reagent, which is a mixture of silver nitrate and ammonia, oxidizes the aldehyde to a carboxylic acid.

What simple ketone is commonly used as a solvent?

Acetone is the simplest and most important ketone. Because it is miscible with water as well as with most organic solvents, its chief use is as an industrial solvent (for example, for paints and lacquers).

Which of the following might result in low levels of Oxaloacetate?

Which of the following might result in low levels of oxaloacetate? Diabetes. Low levels of oxaloacetate may occur if you consume a diet low in carbohydrates, are experiencing starvation conditions, or have diabetes.
