(a)
Interpretation:The mechanism for the formation of molecule 26 from molecule 28 through a hydride shift followed by deprotonation needs to be explained.
Concept Introduction : A carbocation rearrangement in which a hydrogen atom migrates from the carbon to the carbon possessing formal charge of one from the adjacent carbonis called hydride shift.
(b)
Interpretation:The mechanism for formation of 27 from 28 needs to be determined.
Concept Introduction : A carbocation rearrangement in which a hydrogen atom migrates from the carbon to the carbon possessing formal charge of one from the adjacent carbonis called hydride shift.
(c)
Interpretation:The mechanism of formation of 26 through acid catalysed rearrangement of either isomer of 4-methyl-2-pentene and formation of 27 by addition of a proton to 26 followed by deprotonation of intermediate carbocation needs to be explained.
Concept Introduction : A carbocation rearrangement in which a hydrogen atom migrates from the carbon to the carbon possessing formal charge of one from the adjacent carbonis called hydride shift.
(d)
Interpretation:The different in the two types of mechanism for the formation of 26 and 27 needs to be explained.
Concept Introduction:Mechanism of a
