What are haloalkane reactions?
- The reactions of haloalkanes may be divided into the following categories: 1. Nucleophilic substitution 2. Elimination reactions 3. Reaction with metals. (1)Nucleophilic substitution reactions You have learnt in Class XI that nucleophiles are electron rich species.
Are haloalkanes a substrate?
- Haloalkanes are substrate in these reactions. In this type of reaction, a nucleophile reacts with haloalkane (the substrate) having a partial positive charge on the carbon atom bonded to halogen. A substitution reaction takes place and halogen atom, called leaving group departs as halide ion.
Why are Haloarenes less reactive than haloalkanes?
- Thus, C—Cl bond length in haloalkane is 177pm while in haloarene is 169 pm. Since it is difficult to break a shorter bond than a longer bond, therefore, haloarenes are less reactive than haloalkanes towards nucleophilic substitution reaction.
How do tertiary Haloalkanes react with nucleophiles?
- Tertiary haloalkanes alos undergo reaction under similar conditions, but it is found that the concentration of nucleophile does notaffect the rate of the reaction. A strong nucleophile (such as the hydroxide ion) is not necessary. Weak nucleophiles, such as water and alcohol molecules, react readily with tertiary haloalkanes.
