Soruda görsel içerik var: The image shows four chemical structures labeled a, b, c, and ç. All structures consist of a carbon-carbon double bond ($C=C$). - Structure a: Each carbon is bonded to two hydrogen atoms ($H$). - Structure b: The left carbon is bonded to two hydrogen atoms ($H$), the right carbon is bonded to two chlorine atoms ($Cl$). - Structure c: The left carbon is bonded to one $Cl$ and one $H$; the right carbon is bonded to one $H$ and one $Cl$ (positioned trans to each other). - Structure ç: The left carbon is bonded to one $H$ and one $Cl$; the right carbon is bonded to one $Br$ and one $NO_2$ group.
