including the cis or trans designation, what is the iupac name of the following substance? it is not necessary to put cis or trans in italics.

Answer

Explanation:

Step1: Identify the parent - chain

The parent - chain is an alkene with 4 carbon atoms, so the base name is butene.

Step2: Determine the position of the double - bond

The double - bond is between the second and third carbon atoms, so it is 2 - butene.

Step3: Consider the substituents

There are two bromine atoms, one on the second carbon and one on the third carbon.

Step4: Determine the cis/trans configuration

The two higher - priority groups (bromine has a higher priority than methyl and ethyl) are on the opposite sides of the double - bond, so it is trans.

Step5: Write the IUPAC name

The IUPAC name is trans - 2,3 - dibromobutene.

Answer:

trans - 2,3 - dibromobutene
