Concept explainers
(a)
Interpretation:
The given compound should be synthesized from 3,3-dimethyl-l-butene.
In the nucleophilic substitution reaction, the
In
The rate determination step is formation of carbocation.
The stability order of carbocation is,
Tertiary > Secondary > Primary
Therefore, tertiary alcohols undergo substitution very fast than the secondary alcohols because tertiary carbocation is more stable than the secondary carbocation than the primary carbocation. Primary alcohol is less stable therefore it won’t undergoes
(b)
Interpretation:
The given compound should be synthesized from 3,3-dimethyl-l-butene.
Concept introduction:
Meta chloro perbenzoic acid is reaction with alkene which forms the epoxide.
Lithium aluminium hydride is used as a reducing agent.
Lithium aluminium hydride is reduced the epoxide as an alcohol which is shown below.
