Question

Wurtz reaction is used for ascent of series of hydrocarbons. In this reaction, lower alkanes (R—H) convert into higher alkane R—R

R—H →(in presence of) (Br2 /hv) & (—HBr)→ R—Br (Alkyl bromide) →(in presence of) (Na/Dry ether)→ R—R (Alkane)

(1) Methyl bromide through Wurtz reaction gives ethane.

(ii) Ethyl Bromide through Wurtz reaction gives butane.

(iii) A mixture of ethyl and methyl bromide through Wurtz reaction gives a mixture of ethane, propane, butane.

Analyse the given information and give justification in the form of equation using the information given in above statement.

Answer:

1. Methyl bromide experiences Wurtz response to give ethane, (C2H6). 2CH3Br + 2Na = C2H6 + 2NaBr. ... At the point when methyl bromide is treated with sodium within the sight of dry ether, ethane is framed.
2. To convert ethyl bromide to n-butane, we take 2 moles of ethyl bromide with Sodium metal in the presence of dry ether, it results in the formation of n-butane. The above reaction is a named reaction known as Wurtz reaction.
3. By Wurtz reaction, methyl bromide gives ethane in presence of Na metal in dry ether.
