The Activity of Alkyl Groups in Morpholinium Cation on Chemical Reactivity, and Biological Properties of Morpholinium Tetrafluroborate Ionic Liquid Using the DFT Method

The physical properties, chemical and biological properties are evaluated through the Density Functional Theory (DFT) of molecular mechanics. The difference between Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) is starting from -5.91 to 6.15, which means that chemical reactions change the same for all anions. The biological activity of predictions given by QSAR calculation is forecasted where the PIC50 of all ionic liquids is near or less than -4.00, as a result, these are considered as the highly bioactive ionic liquids. To identify these molecules, computational data is used to determine the vibrational and electronic spectrum.
