Concept explainers
(a)
Interpretation: With the mentioned starting material and with any other reagents, an efficient synthesis for compound A has to be proposed.
Concept Introduction:
Retro synthetic analysis:
It is the analysis of the synthetic starting materials for a given compound through its precursors or fragments which are known as synthons. The synthons can be obtained by logical cleavage of the
On retro synthetic analysis of the given compound, the synthetic reaction will be predicted to be azo coupling reaction.
Azo Coupling:
It is an electrophilic
Example:
(b)
Interpretation: The cis isomer for the given trans isomer of
Concept Introduction:
Geometrical isomerism: It is the phenomenon in which any two compounds will found to have same molecular formula with different spatial arrangement of atoms. The major types of geometrical isomers are cis- and trans-isomers.
Cis-isomer: In the cis-isomer, two same
Trans-isomer: In the cis-isomer, two same functional groups will be placed opposite to each other.
