Interpretation Introduction

b)

Interpretation:

How to synthesize trans- 6-methyl-3 heptene from 4-methyl-1-pentyne is to be shown.

Concept introduction:

Higher alkynes can be prepared first by converting the lower alkyne in to an alkynide by reacting with NaNH₂ in liquid NH₃ followed by the reaction of the alkynide with alkyl halide containing the required number of carbon atoms. The higher alkyne thus obtained upon treatment with Li in liquid NH₃ will get reduced to yield a trans alkene as the product.
