Questions & Step-by-Step Solutions
Which of the following is a characteristic of cis isomers?
Step 1: Understand what cis isomers are. Cis isomers are molecules that have similar groups on the same side of a double bond or ring structure.
Step 2: Compare cis isomers to trans isomers. Trans isomers have similar groups on opposite sides.
Step 3: Learn about boiling points. Boiling point is the temperature at which a substance changes from liquid to gas.
Step 4: Know that polarity affects boiling points. Molecules that are more polar tend to have higher boiling points because they attract each other more strongly.
Step 5: Realize that cis isomers are often more polar than trans isomers. This is because the similar groups on the same side create a dipole moment.
Step 6: Conclude that because cis isomers are more polar, they usually have higher boiling points than trans isomers.
