Q1. During a lecture on stereoisomerism, a professor explains why 1-butene does not exhibit cis-trans isomerism despite having a double bond. The reason is:
Answer: Two identical groups on the same carbon
Explanation: 1-Butene lacks geometric isomerism because one terminal carbon has two identical hydrogen atoms. 2-Butene is tempting as it is also an alkene.
