neo-pentyl bromide undergoes nucleophilic substitution reactions very slowly. Justify. |
|
Answer» SOLUTION :(i) `CH_3 - underset(CH_3)underset(|)overset(CH_3)overset(|)C - CH_2Br` neo-pentyl bromide UNDERGOES nucleophilic substitution reactions very slowly due to stéric hindrance of many alkyl groups. When bromide is attached to neo-pentyl carbon atom, the heterolytic cleavage of C-Br takes place very slowly and substitution is also a very SLOW REACTION. (ii) Due to bulky neo-pentyl group, it becomes difficult for a nucleophile to attack from the back side of carbon having C-Br BOND. (iii) Splitting of C-Br gives a primary carbocation which is very less stable. So neo-pentyl bromide undergoes nucleophilic substitution reactions very slowly. |
