I have found Wurtz reaction for primary alkyl halide in my textbook. My textbook also says that only primary and secondary alkyl halide shows Wurtz reaction and tertiary alkyl halides doesn't show Wurtz reaction. I tried to write the Wurtz reaction for secondary alkyl halide which is not included in my textbook. I think the product is quaternary alkane. But I faced a problem. It is: Which type of quaternary alkane is produced in this reaction? Vicinal or Geminal? Please help me in this context.
