A team of researchers is investigating a new carbon-rich molecule important to life. They find evidence for the presence of a carbon-carbon double bond in the molecule. This observation means that the new molecule likely exists as _.

Cis and trans isomers

Explanation:

Existence of double bond in carbon rich compound confirms the presence of geometrical isomer in the compound. The compound showing geometrical isomer exists as cis and trans isomers.

Substituents or functional group around double bond decides that the compound will be cis or trans.

If functional group or bigger substituents are present on the same side of the double bond, the compound will be cis.

If functional group or bigger substituents are present on the opposite of the double bond, the compound will be trans.
