Answer:
The IUPAC name for CH2(OH)-CH2-CH2(OH) is 1,2,3-propanetriol. It is also commonly known as glycerol or glycerin.
Step-by-step explanation:
The IUPAC name for a molecule is a systematic way of naming a compound based on the rules set by the International Union of Pure and Applied Chemistry (IUPAC). In the case of CH2(OH)-CH2-CH2(OH), the IUPAC name is based on the longest carbon chain, which is a three-carbon chain. The -OH groups attached to the carbon chain are named as substituents, with the prefix "hydroxy-" indicating the presence of an -OH group. The first carbon atom in the chain is numbered as "1," and the -OH groups are assigned the lowest possible numbers.
Therefore, the IUPAC name for CH2(OH)-CH2-CH2(OH) is 1,2,3-propanetriol. It is named as propanetriol because it contains a three-carbon chain and three -OH groups. It is also commonly known as glycerol or glycerin and is an important compound used in many industries, including food, cosmetics, and pharmaceuticals.
