a) Interpretation: The change has to be explained when - CN concentration is halved, and the 1-iodo-2-methylbutane concentration is doubled and Both the - CN and the 1-iodo-2-methylbutane concentrations are tripled. Concept introduction: S N 2 reaction: The alcohol is reaction with acids like hydrochloric acid or hydrobromic acid, the bromine atom attacks back side of the carbon atoms in simultaneous manner and which is bearing alcohol group which yield the corresponding product. Example: Alcohol is reaction with tosyl chloride in pyridine which provides retention of configuration of tosylated compound. This tosylated compound is further reaction with sodium methoxide which undergoes again S N 2 type of reaction, the methoxide ion attacks the carbon atom through the back side and provides Inverse configuration of methoxy compound. This is shown below, S N 2 reaction is second order reaction, the rate of the reaction is depending on the both substrate and nucleophiles.

Interpretation Introduction

a)

Interpretation:

The change has to be explained when ^-CN concentration is halved, and the 1-iodo-2-methylbutane concentration is doubled and Both the ^-CN and the 1-iodo-2-methylbutane concentrations are tripled.

Concept introduction:

S_N2 reaction:

The alcohol is reaction with acids like hydrochloric acid or hydrobromic acid, the bromine atom attacks back side of the carbon atoms in simultaneous manner and which is bearing alcohol group which yield the corresponding product.

Example:

Alcohol is reaction with tosyl chloride in pyridine which provides retention of configuration of tosylated compound. This tosylated compound is further reaction with sodium methoxide which undergoes again S_N2 type of reaction, the methoxide ion attacks the carbon atom through the back side and provides Inverse configuration of methoxy compound. This is shown below,

S_N2 reaction is second order reaction, the rate of the reaction is depending on the both substrate and nucleophiles.
