Question 36
Which types of reaction can occur with 1-bromobutane? 1 elimination 2 hydrolysis 3 free radical substitution
Worked Solution & Example Answer:Which types of reaction can occur with 1-bromobutane? 1 elimination 2 hydrolysis 3 free radical substitution - CIE - A-Level Chemistry - Question 36 - 2016 - Paper 1
Step 1
1 elimination
Answer
Elimination reactions occur when a compound loses atoms or groups to form a double bond. For 1-bromobutane, an elimination reaction can occur, particularly when reacted with a strong base such as potassium hydroxide (KOH). This leads to the formation of butene through the E2 mechanism.
Step 2
Step 3
3 free radical substitution
Answer
Free radical substitution involves the replacement of an atom in a molecule with another atom, initiated by free radicals. 1-bromobutane can participate in free radical substitution reactions, especially with halogens like chlorine or bromine under UV light, where hydrogen atoms can be replaced with halogen atoms.
