The compound below is estradiol, a hormone that triggers the development of female secondary sex characteristics. estradiol is best described as which of the following? an alkyne an alkene an alkane an aromatic

Aromatic

Explanation:

Estradiol is an aromatic compound because it is composed on one benzene ring and three cyclohexane ring used to each other. The benzene ring is aromatic. Benzene has 6 pi electrons and a cyclic planar structure.  The number of pi electrons in benzene equals 4n +2.

Huckel's rule: 4n + 2, where n is a positive integer.

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.
