Concept explainers
(a)
Interpretation:
The possibility of open-chain structures of carbohydrates is to be discussed, if so then there classification is to be done.
Concept introduction:
When two molecules have same molecular formula but have different arrangement in space, then they are called to be as isomers.
The carbohydrate can be classified as aldo or keto carbohydrate on the basis of carbonyl groups present in the main chain.
(b)
Interpretation:
The possibility of structures of carbohydrates with four carbon atoms of being isomers is to be discussed, if so then there classification is to be done.
Concept introduction:
When two molecules have same molecular formula but have different arrangement in space, then they are called to be as isomers.
The open-chain structures of carbohydrates can be converted into rings by joining the hydroxyl group with the oxygen of carbonyl group of the chain.
