IUPAC name of CH3CHOHCH2Cl

There are certain rules that must be followed while naming organic compounds. The IUPAC name of CH3CHOHCH2Cl is as follows:

Step 1: Identify the parent chain

The parent chain is the longest continuous chain of carbon atoms. In this case, the parent chain is a three-carbon chain, which is a propane.

Step 2: Number the carbon atoms

Number the carbon atoms in the parent chain so that the functional group has the lowest possible number. In this case, the functional group is the chloro group, which is attached to the second carbon atom. Therefore, the numbering starts from the end nearest to the chlorine atom.

Step 3: Identify and name the substituents

The substituents are the atoms or groups of atoms that are attached to the parent chain. In this case, there are two substituents: a methyl group and a hydroxyl group.

The methyl group is attached to the first carbon atom and is named as "methyl."

The hydroxyl group is attached to the second carbon atom and is named as "hydroxy."

Step 4: Write the name of the compound

Combine the names of the substituents and the parent chain. The name of CH3CHOHCH2Cl is 2-chloropropanol.

Therefore, the IUPAC name of CH3CHOHCH2Cl is 2-chloropropanol.
