Question

Which of the following alkane cannot be made in good yield by wurtz reaction?

• A. n-Heptane
• B. n-Butane
• C. n-Hexane
• D. n-octane

Answer 1

The correct option is A n-Heptane

Wurtz Reaction is limited to the synthesis of symmetrical alkanes(even number of carbon atom). Heptane has odd number of carbon thus it cannot be prepared by wurtz reaction. Hence option (a) is correct.
