Which substances have an enantiomer with a L-configuration? A and C B and C B and C A, B and D

Explanation / Answer

1. Answer ( A )

In carbon cycle glucose and oxygen are converted to carbon dioxide by heterotrophs like large animals. The process is called combustion or metabolism reaction.

2. Answer ( A )

Monosaccharides are the simplest sugar molecules which can not be hydrolysed further .

3. Answer ( D )

Ketopentose as there are 5 carbon atoms and keto group in formula.

4.Answer ( A )

As the option A has six carbon atom and an aldehyde group.

5.Answer ( D )

As compounds A,B and D are D-Configurations hence they will have L- configurations as enantiomers.
