Chapter FRP, Problem 29P

Interpretation Introduction

Interpretation:

The organic product of each of the given reactions is to be predicted.

Concept introduction:

舧 Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles, which accept electron pair.

舧 Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles, which donate electron pair.

舧 Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction.

舧 Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.

舧 Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules.

舧 Reaction sequences involve conversion of one functional group to other, which may also require addition of carbon or loss of carbon from the reactant.

舧 These sequences involve a number of steps carried on by different reagents. Sometimes, different reagents give same products.

舧 The compound methyl magnesium bromide reacts with acetophenone and on subsequent acid treatment gives the product 2-phenylpropan-2-ol.

舧 The alkyl lithium reagents react with ketones and on subsequent work up yields the tertiary alcohols.

舧 The excess methyl magnesium bromide reacts with methyl benzoate and on subsequent acid treatment gives the product 2-phenylpropan-2-ol.
