Question

What is true about the reaction given below? CH3 - CH = CH - CH3 + CH2I2 xrightarrow[Et2O]Zn-Cu (A) Reaction involves a carbocation intermediate (B) Reaction involves a carbanion intermediate (C) Meso or racemic products are formed depending on configuration at double bond (D) Product is an acyclic alkane

Reaction involves a carbocation intermediate

Reaction involves a carbanion intermediate

Meso or racemic products are formed depending on configuration at double bond

Product is an acyclic alkane

Reaction involves $C H_{2}$ intermediate and it undergoes synaddition at double bond, hence stereochemistry of products depends on stereochemistry at double bond as:
