1. a. Calculate the degree of unsaturation in C4H6.
b. Draw at least 4 iosmers with this formula (C4H6).
2. a. Explain why cis dichloroethene has a boiling point of 60 degrees C while trans - dichloroethen has a boiling point of 48 degrees C.
b. Include drawings of the structures with dipoles in your answer.
The solution provides detailed explanations on the concepts of boiling point, isomer and degree of saturation. It also includes the required drawings and illustrations.
