Detail about MCQs
The common name of 1,2,3-propanetriol is C. Glycerol.
- “1,2,3” refers to the carbon atoms in the molecule. In this case, it means that glycerol has three carbon atoms.
- “Propanetriol” is a systematic name that indicates the chemical structure of the compound. “Propane” suggests that it has three carbon atoms in a straight chain, and “triol” indicates that it has three hydroxyl (-OH) groups attached to those carbon atoms.
So, when we combine these pieces of information, “1,2,3-propanetriol” is a systematic way to describe glycerol’s chemical structure, but its common name is simply “Glycerol.”
