Question

НОР - ор -OM
name of this

Answer 1

First to name the given compound,

1)Select the longest carbon chain.

Here the longest carbon chain has four carbons in it.

2) -COOH group is the functional group and it becomes the suffix.

It is -oic acid.

3) Three -OH groups are at second, third and fourth carbons.

They are the substituents.

4)Second and third carbons are chiral carbons.

The configuration at second carbon is R (if the groups on the chiral carbon are arranged in priority order wise based on their atomic number, they are in clockwise direction.)

The configuration at third carbon is R (if the groups on the chiral carbon are arranged in priority order wise based on their atomic number, they are in clockwise direction.)

Hence, the IUPAC name of the given compound is :

(2R,3R)-2,3,4-trihydroxy butanoic acid
