Question

End product of the following sequence of reactions is

CH ≡CH

$\xrightarrow { \mathrm { CH } _ { 3 } \mathrm { MgBr } } \xrightarrow { \mathrm { CO } _ { 2 } / \mathrm { H } _ { 3 } \mathrm { O } ^ { + } } \xrightarrow { \mathrm { HgSO } _ { 4 } / \mathrm { H } _ { 2 } \mathrm { SO } _ { 4 } } \xrightarrow [ \Delta ] { \mathrm { Ag } _ { 2 } \mathrm { O } }$

• A.
• B. CH₂(COOH)₂
• C.
• D.

Answer 1

Answer: (B)

CH₂(COOH)₂

Answer 2

CH ≡ CH + CH₃MgBr → CH ≡ C – MgBr
