From the picture and description can you is that a correct mechanism . can you draw the mechanism ? Phosphate Ester (Minor Product): In the mechanism, a nucleophilic attack by the phosphate ion (�2��4−H2PO4−) substitutes the hydroxyl group in the protonated cyclohexanol. This is a minor product due to steric hindrance. The phosphate group is relatively large and bulky, making the substitution reaction less favored. The size of the substituent may lead to a slower reaction rate and decreased likelihood of successful substitution. Ether (Minor Product): In the mechanism, substitution involves another cyclohexanol molecule attacking the hydroxyl group in the protonated cyclohexanol. Steric hindrance and the availability of a more favorable elimination pathway (dehydration) contribute to the ether being a minor product. The proximity of two cyclohexanol molecules for substitution is hindered by steric factors, making elimination more favorable.

Question

From the picture and description can you is that a correct mechanism . can you draw the mechanism ?

  1. Phosphate Ester (Minor Product):

    • In the mechanism, a nucleophilic attack by the phosphate ion (�2��4−H2PO4−) substitutes the hydroxyl group in the protonated cyclohexanol.
    • This is a minor product due to steric hindrance. The phosphate group is relatively large and bulky, making the substitution reaction less favored. The size of the substituent may lead to a slower reaction rate and decreased likelihood of successful substitution.
  2. Ether (Minor Product):

    • In the mechanism, substitution involves another cyclohexanol molecule attacking the hydroxyl group in the protonated cyclohexanol.
    • Steric hindrance and the availability of a more favorable elimination pathway (dehydration) contribute to the ether being a minor product. The proximity of two cyclohexanol molecules for substitution is hindered by steric factors, making elimination more favorable.

 

1. Phosphate Ester Formation:
C6H11OH2+ + H2PO4-
2. Ether Formation:
Substitution
C6H11OH2+ + C6H110H
C6H11OP (O)(OH)2 + H3O+
Substitution
C6H11OC6H11 + H3O+
