(a)
Interpretation:
The reagent must be provided to achieve the given transformation.
Concept Introduction :
The OTs group is a good leaving group which can be displaced by simple nucleophilic substitution.
(b)
Interpretation:
The reagent must be provided to achieve the given transformation of alcohol to cyano compound.
Concept Introduction :
The OH group is a bad leaving group which can be displaced by cyanide after converting the OH to a good leaving group.
(c)
Interpretation:
The reagents must be provided for the conversion of tertiary alcohol to tertiary bromide.
Concept Introduction :
The tertiary alcohols can undergo acid catalyzed SN1 substitution.
(d)
Interpretation:
A suitable reagent must be provided for the conversion of chloro to thiol with inversion of configuration.
