<prompt> Spatial relationship of every atom in a molecule is known as:ConformationConfigurationBoth of the aboveNone of the above  <response>: The terms configuration and conformation are often confused:Configuration refers to the geometric relationship between a given set of atoms, for example, those that distinguish l- from d-amino acids. Interconversion of configurational alternatives requires breaking and reforming covalent bonds.Conformation refers to the spatial relationship of every atom in a molecule.Ref: Harpers illustrated biochemistry. 30th edition page no: 36
