Important Topics for MS Chauhan Organic Chemistry Solutions Chapter 5A Alkyl Halides (Substitution Reaction)
Alkyl halides refer to the organic compounds consisting of halogen atoms as a substituent. They are also called as haloalkanes that are the mixtures in which one or more hydrogen atoms in an alkane have been substituted by halogen atoms such as fluorine, bromine, chlorine, or iodine.
Physical Properties of Alkyl Halides
Alkyl halides consist of higher boiling points because of their high molecular weight. For a certain alkyl group, the boiling point rises with the increase in the atomic weight of the halogen, where fluoroalkanes have the minimum boiling point and iodoalkanes have the maximum boiling point. They are unsolvable in water generally due to their inability to form hydrogen bonds. They are solvable in typical organic solvents.
Substitution reaction refers to a chemical reaction during which one functional group in a chemical compound is substituted by another functional group. Substitution reactions are of major significance in organic chemistry.
Substitution Reaction Example
Substitution reaction is a type of chemical reaction that is said to own prime importance in the field of organic chemistry. For example, when CH3Cl is responded with the hydroxyl ion (OH-), it will lead to the creation of the original molecule known as methanol with that hydroxyl ion. The following reaction is as represented below:
CH3Cl + (−OH) ——— -CH3OH (methanol) + Cl-
One more example would be the reaction of Ethanol with the hydrogen iodide which generates iodoethane along with water. The reaction is as represented below:
CH3CH2OH + HI ———— CH3CH2OI + H2O
Substitution Reaction Conditions
In order for substitution reaction to happen there are definite situations that have to be used. They are mentioned below:
- Preserving low temperatures including room temperature
- The strong base including NaOH has to be in dilute form. Assume if the base is of a greater concentration, there are risks of dehydrohalogenation taking place.
- The solution needs to be in an aqueous state including water.
Types of Substitution Reactions
Generally, there are two types of substitution reactions including nucleophilic reactions and electrophilic reactions. These two types of reactions generally vary in the kind of atom which is attached to its unique molecule. In the nucleophilic reactions, the atom is considered to be electron-rich species, where, in the electrophilic reaction, the atom is an electron-deficient species. A brief description of the two types of reactions is as provided below.
