(a)
Interpretation:
Reagents and experimental conditions by which an oxanamide can synthesized from butanal has to be shown.
Concept introduction:
Acid chlorides are most often prepared by treating a
Alkyl or aryl magnesium halides (RMgX) are known as Grignard reagent. The Grignard reaction is an organometallic
Reaction of Grignard reagent with a formic ester followed by hydrolysis in aqueous acid yields secondary alcohol. Tertiary alcohol can be prepared by the reaction of Grignard reagent with ester other than formate.
(b)
Interpretation:
The number of chiral centers and stereoisomers possible for the given compound has to be shown.
Concept introduction:
Chiral centre:
A chiral centre is defined as the tetrahedral carbon atom in an organic molecule that is connected to four non-identical groups/substituents. It is sometimes known as a stereo genic centre.
Stereoisomers: Two compounds with same molecular formula but different in their orientation are considered as isomers.
Number of possible stereoisomers for a compound can be determined as,
