order of reactivity of alkyl halides
Which alkyl halides are most reactive?
In general, alkyl halides with a primary (1º) carbon-halogen bond, such as CH3I, are the most reactive, followed by secondary (2º) alkyl halides, such as (CH3)2CHBr, and then tertiary (3º) alkyl halides, such as (CH3)3CBr.
What is the relative reactivity of alkyl halides?
Relative reactivity of alkyl and aryl halides in nucleophilic-substitution reactions.
In case of alkyl halides, the order for relative rates of reactions is RI>RBr>RCl.Explanation:Reactivity of halides towards SN1 mechanism is benzyl > allyl > 3o > 22 > 1o.
What is the order of reactivity of alkyl halides assertion?
The order of reactivity is RI >RBr>RCl> RF.
Assertion: Ammonolysis of alkyl halides involves reaction between alkyl halides and alcoholic ammonia.
Reason: Ammonolysis of alkyl halides mainly produces 2 ∘ amines.
