$Ph-(CH_2)_5-NH_2$

Vedclass · Answer

(C) The starting material is $5-oxo-5-phenylpentanamide$ $(Ph-CO-(CH_2)_3-CONH_2)$.Step $1$: Clemmensen reduction $(Zn/Hg, HCl)$ specifically reduces the ketone group to a methylene group $(-CH_2-)$ while leaving the amide group intact.This yields $5-phenylpentanamide$ $(Ph-(CH_2)_4-CONH_2)$.Step $2$ and $3$: Treatment with $LiAlH_4$ followed by acidic workup $(H_3O^+)$ reduces the amide group $(-CONH_2)$ to a primary amine $(-CH_2NH_2)$.The final product is $5-phenylpentan-1-amine$ $(Ph-(CH_2)_5-NH_2)$.Thus,the correct option is $C$.
