Concept explainers
(a)
Interpretation:
A suitable reagent should be predicted for the given transformations.
Concept introduction:
Elimination reaction: In this reaction, two substituents are removed from the substrate to give the product in presence of base.
Anti-Markovnikov’s rule: unsymmetrical
(b)
Interpretation:
A suitable reagent should be predicted for the given transformations.
Concept introduction:
Hydrobromination:
A hydrobromination reaction is one of the electrophilic additions to alkenes to yield the corresponding bromo
(c)
Interpretation:
A suitable reagent should be predicted for the given transformations.
Concept introduction:
Osmium tetra oxide:
Cis-alkene undergoes oxidation using osmium tetra oxide followed by hydrogen peroxide hydrolysis which furnish cis 1,2
(d)
Interpretation:
A suitable reagent should be predicted for the given transformations.
Concept introduction:
Elimination reaction: In this reaction, two substituents are removed from the substrate to give the product in presence of base.
Anti-dihydroxylation: It is a process of adding two –OH groups from different planes to the alkene. Alkenes are treated with peroxy acids followed by aqueous acids and gives anti-dihydroxylation products.
Syn-dihydroxylation: It is a process of adding two –OH groups from the same plane to the alkene. Potassium per manganite and osmium tetroxide etc, are used as reagents.
