Question
Chapter 7, Problem 6PP
Interpretation Introduction
Interpretation:
The formation of major product when 2-bromobutane is subjected to dehydrobromination using sodium ethoxide in ethanol at
Concept introduction:
The stability of
The stability of alkene increases as the number of alkyl group attached to the carbon atom of double bond increases.
According to the Zaitsev’s rule, in the presence of small base like hydroxide or ethoxide the more highly substituted alkene will be the major product.
