A is a d-aldohexose and B is an L-aldohexose. they afford the same optically active aldaric acid after dilute nitric acid oxidat
Alexeev081 [22]

Answer:

D-Glucose and L-Glucose

Explanation:

Aldohexose are the sugars which have six number of carbons and ends up in having an aldehyde group at one end. When dilute nitric acid is treated with any of them, the molecule gets oxidized (gets oxygen) and therefore turns into carboxylic acid.

The name of A is D-Glucose, and B is L-Glucose. Please find the structural formula attached.

Name the following compound:
igomit [66]

Answer:

3,5-dimethyl-2-octene

Explanation:

When naming an organic molecule with a double bond, the chain has to include the double bond.  This means that there are 8 carbon atoms on the central chain.  The molecule is octene.  The double bond is after the second carbon, making it 2-octene.  You can't say that its 6-octene because you want to have the smallest number possible in front.

The molecules attached are two methyl groups.  Since you have two methyl groups, the name will be dimethyl.  Start counting from the side closest to the double bond.  This gives you a 3, 5-dimethyl group.
