Question

CH4 is not obtained by,

1.Wurtz reaction
2.corey-house synthesis
3.recdiction of alkylhalide
4.kolbe's electrolysis​

Answer 1

Answer:methane is not obtained by

option 1)Wurtz reaction

option 4)kolbes electrolysis

option 2)Corey -house synthesis

methane can only be prepared by reduction of alkyl halides

hope it helps you

Answer 2

CH₄ is not obtained by Wurtz reaction.

• The corey house synthesis forms an alkane from the reaction alkyl halides with lithium divinylcuprate.
• Alkanes can also be prepared by reduction of alkyl halides , the reaction is as follows:

CH-Br + 2Na + BrCH₃ dry ether CH₃-CH₃ + 2NaBr

• Wurtz reaction is a similar reaction with sodium metal but can only produce alkanes with even number of carbons. Therefore we cannot get CH₄ from it.
• Kolbe's reaction can also produce alkanes by electrolysis.
