When the concentration of alkyl halide is tripled and concentration of OH is reduced to half, the rate of SN2 reaction increased by:

For N S 2 reaction, ∴If concentration of R – X is tripled and - OH is halved, rate will become 1.5 times. 26. C3H8 + Cl2 C3H7Cl + HCl is an example of which of the following types of reactions (a) Substitution (b) Elimination (c) Addition (d) Rearrangement This is an example of free radical substitution reaction hydrogen atom of alkane is replace by halogen atom. 27. 2, 6 - Dimethylheptane on monochlorination produces……. derivatives (a) 5 (b) 6 (c) 3 (d) 4 2,6 - Dimethylheptane is a disubstituted alkane. Two methyl groups are attached to the second and sixth carbon atoms on the chain,
