Question

Give the common name for the structure. ethyl isopropyl ketone tert-butyl ethyl ketone sec-butyl ethyl ketone ethyl isobutyl ketone isobutyl methyl ketone

Answer 1

Common names for ketones include the names of the alkyl groups attached to the carbonyl group followed by 'ketone'. Ethyl methyl ketone is an example with an ethyl group and a methyl group.

Step-by-step explanation:

The common names for ketones are typically derived by naming the alkyl groups attached to the carbonyl group, followed by the word ketone. For the ketones listed:

• Ethyl isopropyl ketone refers to a ketone with an ethyl group and an isopropyl group attached to the carbonyl.
• Tert-butyl ethyl ketone has a tertiary butyl group and an ethyl group attached.
• Sec-butyl ethyl ketone consists of a secondary butyl group and an ethyl group attached.
• Ethyl isobutyl ketone has an ethyl group and an isobutyl group attached.
• Isobutyl methyl ketone, also known as 3-methyl-2-butanone, has an isobutyl group and a methyl group attached.

For example, the ketone with four carbon atoms, with an ethyl group and a methyl group on either side of the carbonyl, is commonly known as ethyl methyl ketone.

Answer 2

The structure for this question is attached. I think the correct answer would be the fourth option. The common name of the structure would be ethyl isobutyl ketone. Other name would be 2-methyl-3-pentanone. It has a chemical formula of C7H14O or (CH3)2CHCH2C(O)CH2CH3. It is classified as an aliphatic ketone and is used as a solvent and a reagent in laboratory experiments. It is a VOC or volatile organic compound. This compound can also be found at times in normal human biofluids and in feces for about 25% of the population. At normal conditions, it exists as a solid compound.
