Connectivity

Term · Chemistry · MLC-T-CHM-002450

The description of the bonding sequence between atoms in a molecule, specifying which atoms are bonded to which, irrespective of the nature of the bonds. It defines the constitution of a molecule without regard to stereochemistry or bond order. For example, both ethanol (CH₃CH₂OH) and dimethyl ether (CH₃OCH₃) have the same atomic composition but different connectivity.
