Define this ?Name the alkene below.Use ONLY E/Z designators to indicate stereochemistry.H2C=C=CHCH3From studies of the dipole moment of 1,2-dichloroethane in the gas phase at room temperature (25°C), it is estimated that the ratio of molecules in the anti conformation to gauche conformation is 7.6 to 1. Calculate the difference in Gibbs free energy between these two conformations.
