Predict the order of reactivity of the following compounds in dehydrohalogenation:
(a) `CH_(3)CH_(2)CH_(2)CH_(2)Cl, (CH_(3))_(2)CHCH_(2)Cl, (CH_(3))_(2)CH-CH_(2)Br, CH_(3)CH(Br)CH_(2)CH_(3), (CH_(3))_(3)C-Br`
(b) `CH_(3)CH(Br)CH_(3), CH_(3)CH_(2)CH_(2)Br, (CH_(3))_(2)CHCH_(2)Br, (CH_(3))_(3)C CH_(2)Br`

Text Solution

AI Generated Solution

To predict the order of reactivity of the given compounds in dehydrohalogenation, we need to consider the stability of the resulting alkenes and the leaving ability of the halides. The general trend is that tertiary halides react faster than secondary halides, which in turn react faster than primary halides. Additionally, bromides are generally better leaving groups than chlorides. ### Part (a) The compounds given are: 1. `CH₃CH₂CH₂CH₂Cl` (1-bromobutane) 2. `(CH₃)₂CHCH₂Cl` (2-chlorobutane) 3. `(CH₃)₂CH-CH₂Br` (2-bromobutane) ...
