Question

Consider the following reaction and possible products. The major product(s) are best described as:

a) A mixture of A and B with B dominating
b) C only
c) D only
d) As a mixture of diastereomers
e) E only as a mixture of diastereomers

Answer 1

The major product of a dimerization reaction where 2A → product is a dimer named after the monomer followed by 'dimer.' This reaction is classified as synthesis because it combines two monomer units into a more complex molecule. The option (C) is correct.

Step-by-step explanation:

The student's question pertains to reaction products and their distribution in a chemical reaction. When two molecules of reactant 'A' react, the possible products are a mixture of two or more compounds. In this case, the student is asked to describe the major product(s) of a reaction where the rate is proportional to the concentrations of two reactants, typically represented as A + B → products.

Considering an example like the dimerization reaction (2A → product), the major product is the dimer formed from two monomer units. The systematic name of a monomer like 2,5-dimethyl-3,4-diphenylcyclopentadienone would lead to a dimer named after the monomer followed by 'dimer.' In this context, the reaction is synthesis because it involves the combination of two or more reactants to form a new, more complex product.

Product Formation and Reaction Classification

1. The product formed in a dimerization reaction is often referred to as the 'dimer' - the monomer name followed by 'dimer.'
2. The reaction is classified as a synthesis reaction which results in the formation of a more complex compound from simpler reactants. Therefore, option (C) is correct.
