Ethylene (C2H4) has a structure where two carbon atoms are joined by a double bond, and each carbon atom is also bonded to two hydrogen atoms (H2C=CH2). - The geometry around each carbon atom can be predicted using VSEPR theory. Each carbon atom is bonded to three other atoms (one carbon and two hydrogens), and there are no lone pairs on the carbon atoms involved in sigma bonding to other atoms. - The three electron domains around each carbon (one double bond, two single bonds) arrange themselves as far apart as possible, resulting in a trigonal planar geometry around each carbon. The ideal bond angles are approximately 120 degrees. - Because of the rigidity of the double bond and the trigonal planar arrangement around each carbon, all six atoms in the ethylene molecule lie in the same plane. - Thus, the molecule is planar (coplanar), and the bond angles around each carbon are roughly 120 degrees, resembling a triangle. "Coplanar triangular" accurately describes this shape.
In ethylene which of the following shape is acquired by the molecule ?
