Vedclass · Answer

(B) The reaction of an ether with $PCl_5$ involves the cleavage of the $C-O$ bond. For an alkyl aryl ether like phenyl cyclohexyl ether $(Ph-O-C_6H_{11})$,the $C-O$ bond between the alkyl group and oxygen is cleaved,while the $C-O$ bond between the aryl group and oxygen is very strong due to partial double bond character and is not easily cleaved. The reaction proceeds as follows: $Ph-O-C_6H_{11} + PCl_5 \rightarrow Ph-O-PCl_4 + C_6H_{11}Cl$ Further,$Ph-O-PCl_4$ can decompose to form $PhCl$ and $POCl_3$. However,phenol $(C_6H_5OH)$ is not a product of this reaction as the aryl-oxygen bond does not break under these conditions to form the alcohol. Thus,$C_6H_5OH$ is not a product.

Which of the following is not a product of the reaction between phenyl cyclohexyl ether and $PCl_5$?
