Show Answer
Answer:
Correct Answer: B
Solution:
- $ CH _3CH _2CH _2Br+KOH\to CH _3CH $ $ =CH _2+KBr+H _2O $ breaking of $ 2\sigma $ bonds and formation of 1 $ 1\pi $ bond so it is an example of elimination reaction. replacement of $ B{r^{-}} $ by $ O{H^{–}} $ is substitution reaction breaking of $ 1\pi $ bond and formation of $ 2\sigma $ bonds is addition reaction
