Question

The compound (1) in the following sequence of reactions is a silver salt of

A B $\xrightarrow [ \mathrm { EtOH } ] { \mathrm { KOH } }$ propene

• A. Propanoic acid
• B. Butyric acid
• C. Isobutyric acid
• D. Both (2) and (3)

Answer 1

Answer: (D)

Both (2) and (3)

Answer 2

(1) $\xrightarrow [ \substack { - \mathrm { CO } _ { 2 } \\ - \mathrm { AgBr } } ] { \mathrm { CCI } _ { 4 } }$ CH3 —

CH2 — Br CH2 = CH2 ethene

(2) $\xrightarrow [ \substack { - \mathrm { CO } _ { 2 } \\ - \mathrm { AgBr } } ] { \mathrm { CCI } _ { 4 } }$ CH3 — CH2 — CH2 — Br $\mathrm { CH } _ { 3 } - \mathrm { CH } = \mathrm { CH } _ { 2 }$ Propene

(3) $\xrightarrow [ \substack { - \mathrm { CO } _ { 2 } \\ - \mathrm { AgBr } } ] { \mathrm { CCI } _ { 4 } }$

$\xrightarrow [ \mathrm { EtOH } ] { \mathrm { KOH } }$ $\mathrm { CH } _ { 3 } - \mathrm { CH } = \mathrm { CH } _ { 2 }$ Propene
