The `S_(N)2` reaction of 1-chloro-3-methylbutane with sodium methoxide is relatively slow , but can be accelerated by the addition of a small amount of Nal . How is this catalysis best explained ?

The decomposition of H_2O_2 can be slowed down by the addition of small amount of phosphoric acid which act as :

The hydrolysis of 2-bromo-3-methylbutane by S_N1 mechanism gives mainly

The hydrolysis of 2-bromo-3-methylbutane by S_(N^(1)) mechanism gives meinly:

Assertion : Tert : butyl halide with sodium methoxide will not give appreciable amount of tert: butyl methyl ether. Reason : The reaction between alkoxide and alkyl halide that produces ether is an S_(N)2 reaction.

Explain S_(N)2 reaction mechanism of haloalkane. Arrange the reactivity of 1^(@), 2^(@) and 3^(@) haloalkane towards S_(N)2 reaction.

Explain S_(N)2 reaction mechanism of haloalkane. Arrange the reactivity of 1^(@), 2^(@) and 3^(@) haloalkane towards S_(N)2 reaction.

Addition of HCl to 3,3-dimethyl-1-butene and reaction of HCl with 3,3-dimethyl-2-butanol give the same product. Explain,
