Yellow ball=hydrogen atom
Black ball=carbon atom
Wood stick=polar covalent bond
Spring=covalent bond
The photograph shows ethene which has formula of C2H4. We think that two bent or V- shaped structures double bonding each other at carbon atom forms ethene. To be specific, the reason wht there is one bent structure is because there are still one lone pair that causes other two hydrogen atoms to form V-shape. It is also based on two hydrogen atoms attaching to one carbon atom. There is a single bond between hydrogen atom and carbon atom in order to follow duet rule for hydrogen atom. In other hand, there are two double bond between two bent shape structure at carbon atom in order to follow octet rule. Nevertheless, other researches have shown that ethene has form of alkenes.
