Question

be sure to answer all parts. rank the species in order of increasing nucleophilicity in acetone. a. ch3sh b. ch3oh c. ch3nh2

Answer 1

In acetone, the species can be ranked in order of increasing nucleophilicity as follows: CH3OH, CH3SH, CH3NH2.

Step-by-step explanation:

In acetone, the species can be ranked in order of increasing nucleophilicity as follows:

1. CH3OH - Methanol. The oxygen atom in methanol makes it a stronger nucleophile than the other two species.
2. CH3SH - Methanethiol. Sulfur is less electronegative than oxygen, so methanethiol is a weaker nucleophile than methanol.
3. CH3NH2 - Methylamine. Nitrogen is less electronegative than sulfur, so methylamine is the weakest nucleophile among the three species in acetone.

Answer 2

The order of increasing nucleophilicity in acetone is CH3OH, CH3SH, CH3NH2.

Step-by-step explanation:

In order to rank the species in order of increasing nucleophilicity in acetone, we need to consider the relative nucleophilic strength of the different species. Nucleophilicity is generally related to the ability of a species to donate an electron pair. Higher nucleophilicity corresponds to a stronger ability to donate electrons. Among the given species, the order of increasing nucleophilicity in acetone would be:

1. CH3OH
2. CH3SH
3. CH3NH2

Step-by-step explanation:

• CH3OH (methanol) is more nucleophilic than CH3SH (methanethiol) because oxygen is more electronegative than sulfur, making the oxygen more willing to donate its electron pair.
• CH3SH is more nucleophilic than CH3NH2 (methylamine) because sulfur is more polarizable than nitrogen, allowing the sulfur to better accommodate an extra electron pair.
