I.     NO2C6H5−CH=CH2\mathrm{I}\mathrm{.}\,\,\,\,\,\mathrm{N}{\mathrm{O}_2}{\mathrm{C}_6}{\mathrm{H}_5} - \mathrm{CH} = \mathrm{C}{\mathrm{H}_2}
II.     CH2=CH−C6H5CH3\mathrm{II}\mathrm{.}\,\,\,\,\,\mathrm{C}{\mathrm{H}_2} = \mathrm{CH} - {\mathrm{C}_6}{\mathrm{H}_5}\mathrm{C}{\mathrm{H}_3}
III.     CH2=CH−C6H5OCH3\mathrm{III}\mathrm{.}\,\,\,\,\,\mathrm{C}{\mathrm{H}_2} = \mathrm{CH} - {\mathrm{C}_6}{\mathrm{H}_5}\mathrm{OC}{\mathrm{H}_3}
