Q13. Molecules must collide with enough energy to begin to break the old bonds so new bonds can form. 70. If the alkyl halides be bulky in nature, especially at the halogen end, there is a greater amount of alkene formed. This is because the alkyl halides when they react with each other also react within themselves and give rise to other unnecessary products as they will undergo rearrangement and elimination reactions too. Which catalyst is used in Wurtz-Fittig reaction? reactant. A reaction related to the Wurtz Reaction in which aryl halides are used instead of alkyl halides is often called the Wurtz-Fittig reaction and is a very important named reaction in organic chemistry. If the alkyl halide has more chemical reactivity than the aryl halide, it will form the carbon sodium bond first and act as a nucleophile to the aryl halide, helping the reaction in forming asymmetrical products.
