Order of Reactivity towards Nucleophilic Addition to Carbonyl Group
Cyclopentanone, 3-pentanone, and n-pentanal are all carbonyl compounds that can undergo nucleophilic addition reactions. The decreasing order of reactivity towards nucleophilic addition to the carbonyl group among these compounds is as follows:
1. n-Pentanal
2. Cyclopentanone
3. 3-Pentanone
Explanation:
1. n-Pentanal:
n-Pentanal contains an aldehyde group (-CHO) which is more reactive than a ketone group (-C=O) towards nucleophilic addition reactions. This is because the carbonyl carbon in an aldehyde is more electrophilic due to the absence of a carbon atom carrying two electron-withdrawing groups. Therefore, n-pentanal is the most reactive towards nucleophilic addition reactions among the given compounds.
2. Cyclopentanone:
Cyclopentanone contains a ketone group (-C=O) which is less reactive than an aldehyde group (-CHO) towards nucleophilic addition reactions. However, the cyclic structure of cyclopentanone makes its carbonyl carbon less accessible to nucleophiles, which further decreases its reactivity towards nucleophilic addition reactions.
3. 3-Pentanone:
3-Pentanone also contains a ketone group (-C=O) which is less reactive than an aldehyde group (-CHO) towards nucleophilic addition reactions. Moreover, 3-pentanone has a linear structure which makes its carbonyl carbon more accessible to nucleophiles than cyclopentanone, but still less reactive than n-pentanal.
Therefore, the decreasing order of reactivity towards nucleophilic addition to the carbonyl group among cyclopentanone, 3-pentanone, and n-pentanal is n-pentanal > cyclopentanone > 3-pentanone.
