Question

which one of the following alkane is not formed in wurtz reaction (a)methane (b) ethane (c) propane (d) butane​

Answer 1

Answer:

The answer is

(a)Methane

Answer 2

Methane cannot be prepared by wurtz reaction since the products of wurtz reaction are alkanes with atleast 2 carbon atoms. Methane being the simplest alkane with only a single carbon atom, cannot be prepared by Wurtz.

Note: Even though propane can be formed by wurtz between ethane and methane, ethane and butane are also formed as by products and seperation of propane is difficult. So wurtz is not acually a suitable method to prepare propane. So refrain from using wurtz reaction to prepare propane especially in conversion questions.
