Which functional group is found in an amine? A central carbon is double bonded to O above, and single bonded to R below left and to O single bonded to R below right.
N is single bonded to R, and single bonded twice to H.

A central carbon is double bonded to O above, and single bonded to R below left and to R prime below right.
A central carbon is double bonded to O above, and single bonded to R below left and to H below right.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
