Chapter 9.8, Problem 11P

Interpretation Introduction

Interpretation:

Starting from propyne and using an alkyl halide and other reagents needed, how cis-2-butene can be prepared is to be stated.

Concept introduction:

Alkenes can be prepared by the reduction of alkynes using hydrogen in the presence of Lindlar catalyst. Higher membes of alkyne series can be obtained by the alkylation of terminal alkynes with primary alkyl halides.

To state:

Starting from propyne using an alkyl halide and other reagents needed, how cis-2-butene can be prepared.
