Which of the following is the simplest ketone used as an organic solvent?

Lyrx [107]

Answer: Option (d) is the correct answer.

Explanation:

A ketone is an organic functional group that contains a carbon and oxygen atom bonded together through a double bond, that is, C=O.

For example, acetone $CH_{3}-CO-CH_{3}$ is a ketone.

Whereas a hydrocodone is a drug which is used to relieve from moderate to sever pain.It is mostly combined with other drugs and resulting in a chemical formula $C_{18}H_{21}NO_{3}.C_{4}H_{6}O_{6}$ .

A camphor is a volatile white color substance with chemical formula $C_{10}H_{16}O$ . It has aromatic smell and its taste is bitter.

A menthone is also an organic compound with chemical formula $C_{10}H_{18}O$ .

Thus, we can conclude that out of the given options the simplest ketone used as an organic solvent is acetone.

What effect does rapid exhalation of CO2 during exercise have on the concentration of H2CO3 in the blood?

BARSIC [14]

If there is a constant loss of $CO_{2}~(carbon~dioxide)$ the concentration of $H_{2} CO_{3}~(carbonic~acid)$ will be affected and decrease since $CO_{2}$ is a main component of $H_{2}CO_{3}$ .
