Question

convert propene to 2,3-dimethylbutane ?

Answer 1

The conversion between propene and 2,3-dimethylbutane is given below :-

1> first treat the Propene with HBR to form 2-bromopropane. 
2>In second step treat it with Na in the presence of dry ether to get 2,3-dimethyl butane.

Answer 2

Answer: The conversion is given below.

Explanation:

For the conversion of propene to 2,3-dimethylbutane, we follow some steps:

Step 1: Conversion of propene to 2-bromoethane

When propene is reacted with HBr, the negative part (Bromine) will go to the carbon atom where less number of hydrogen atoms are present. This rule is known as Markonikov's rule.

Step 2: Conversion of 2-bromoethane to 2,3-dimethylbutane

When 2-bromoethane is reacted with sodium metal in the presence of dry ether, it results in the formation of 2,3-dimethylbutane. This reaction is known as Wurtz reaction.

The equations for the conversion is given in the image attached.
