To determine: Acetone and propanal are which type of isomers.
Concept introduction: Isomers are defined as two or more molecules that have the same number of atoms but their arrangements are different. They differ in properties due to different atomic arrangements in molecules.
To determine: The number of asymmetric carbons that are present in glycerol phosphate, acetic acid, and glycine.
Concept introduction: Isomers are defined as two or more molecules that have the same number of atoms but their arrangements are different. They differ in properties due to different atomic arrangements in molecules.
To determine: Whether acetic acid, glycine, and glycerol phosphate exist as enantiomers.
Concept introduction: Isomers are defined as two or more molecules that have the same number of atoms but their arrangements are different. They differ in properties due to different atomic arrangements in molecules.
