Chemistry - Halogen Derivative Question with Solution | TestHub

The product obtained in the first reaction can be either CH₃CH₂CH₂OH or CH₃CH=CH₂, which is a result of substitution or elimination respectively. If reaction occurs at 20°C, substitution would dominate elimination, as elimination is favoured only at high temperature. At 80°C, the elimination product is predominant and the subsequent reaction of addition of HBr to alkene at low temperature would be greatly favoured.
