To determine which statement is incorrect for cis-but-2-ene relative to trans-but-2-ene, we need to analyze the properties of both isomers based on their molecular structure and how this affects their physical properties.1. Identify the
14 Which compound has E-Z isomers? B A but-1-ene B but-2-ene C 1,1-dichloroethene D 2-methylbut-2-ene 相关知识点: 试题来源: 解析 B14The only correct answer is BA is not correct because in the double bond the first C atom has 21 ttached C is not correct because in the d...
