Vedclass · Answer

(D) The synthesis of hexanal $(C_6H_{12}O)$ can be achieved by the reaction of a Grignard reagent with ethylene oxide followed by oxidation. Step $1$: $CH_3CH_2CH_2CH_2MgBr + C_2H_4O \rightarrow CH_3CH_2CH_2CH_2CH_2CH_2OMgBr$. Step $2$: Acidic workup $(H_3O^{+})$ yields $1$-hexanol $(CH_3CH_2CH_2CH_2CH_2CH_2OH)$. Step $3$: Oxidation of the primary alcohol with $PCC$ (Pyridinium chlorochromate) in $CH_2Cl_2$ gives hexanal $(CH_3CH_2CH_2CH_2CH_2CHO)$.

Which sequence represents the best synthesis of hexanal?
$CH_3CH_2CH_2CH_2CH_2CH=O$ (Hexanal)
