Concept explainers
(a)
Interpretation: Reagents are needed to convert 2-methylpropene
Concept introduction: Dihalocarbenes can be formed from the reaction of chloroform with a strong base. They are electron deficient molecules which can attack an electron rich molecule like
(b)
Interpretation: Reagents are needed to convert 2-methylpropene
Concept introduction: Dihalocarbenes can be formed from the reaction of chloroform with a strong base. They are electron deficient molecules which can attack an electron rich molecule like alkene. The product of this reaction is a cyclopropane substituted alkene.
(c)
Interpretation: Reagents are needed to convert 2-methylpropene
Concept introduction: Dihalocarbenes can be formed from the reaction of chloroform with a strong base. They are electron deficient molecules which can attack an electron rich molecule like alkene. The product of this reaction is a cyclopropane substituted alkene.
