Which of the following reagents are not correctly matched with the reaction?

A

CH3CH=CHCHO\mathrm { CH } _ { 3 } \mathrm { CH } = \mathrm { CHCHO } \rightarrow CH3CH=CHCOOH\mathrm { CH } _ { 3 } \mathrm { CH } = \mathrm { CHCOOH }: Ammoniacal AgNO3\mathrm { AgNO } _ { 3 }

B

CH3CH=CHCHO\mathrm { CH } _ { 3 } \mathrm { CH } = \mathrm { CHCHO } \rightarrow CH3CH=CHCH2OH:H2/Pt\mathrm { CH } _ { 3 } \mathrm { CH } = \mathrm { CHCH } _ { 2 } \mathrm { OH } : \mathrm { H } _ { 2 } / \mathrm { Pt }

C

RCOOHRCH2OH:NaBH4\mathrm { R } - \mathrm { COOH } \rightarrow \mathrm { R } - \mathrm { CH } _ { 2 } \mathrm { OH } : \mathrm { NaBH } _ { 4 }

D

CH3CH2COClCH3CH2CHO:H2Pd/BaSO4\mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { COCl } \rightarrow \mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { CHO } : \mathrm { H } _ { 2 } \mathrm { Pd } / \mathrm { BaSO } _ { 4 }

Answer

CH3CH=CHCHO\mathrm { CH } _ { 3 } \mathrm { CH } = \mathrm { CHCHO } \rightarrow CH3CH=CHCH2OH:H2/Pt\mathrm { CH } _ { 3 } \mathrm { CH } = \mathrm { CHCH } _ { 2 } \mathrm { OH } : \mathrm { H } _ { 2 } / \mathrm { Pt }

Explanation

Solution

: CH3CH=CHCHOH2/PtCH3CH=CHCH2OH\begin{aligned} \mathrm { CH } _ { 3 } \mathrm { CH } = & \mathrm { CHCHO } \xrightarrow { \mathrm { H } _ { 2 } / \mathrm { Pt } } \\ & \mathrm { CH } _ { 3 } \mathrm { CH } = \mathrm { CHCH } _ { 2 } \mathrm { OH } \end{aligned}
