consider the substitution reaction of (r)-3-chloro-3-methylhexane with methanol and heat. r 3 chloro 3 methyl hexane is treated with methanol to give four possible products. all have substituents on carbon 3. the structure of the starting material is a 6 carbon chain with a methyl group pointing towards the viewer and a chloro group pointing away from the viewer. compound a has a methoxy group pointing towards the viewer and a methyl group pointing away from the viewer. compound b has a methyl group pointing towards the viewer and a hydroxy group pointing away from the viewer. compound c has a hydroxy group pointing towards the viewer and a methyl group pointing away from the viewer. compound d has a methyl group pointing towards the viewer and a methoxy group pointing away from the viewer. identify the substitution product(s). a b c d no reaction

Answer :

The possible products of the Substitution reaction of (r)-3-chloro-3-methylhexane with methanol and heat are A and D.

The substitution reaction of (r)-3-chloro-3-methylhexane with methanol and heat is a nucleophilic substitution reaction. In this reaction, the chlorine atom in (r)-3-chloro-3-methylhexane acts as the leaving group, while the methanol serves as the nucleophile. The reaction proceeds through a series of steps:

1. The chlorine atom in (r)-3-chloro-3-methylhexane is protonated by the hydrogen atom in methanol. This creates a positively charged carbon-chlorine bond.

2. The nucleophilic attack of the methanol molecule onto the positively charged carbon-chlorine bond results in the formation of a covalent bond between the two molecules.

3. The newly formed covalent bond is then broken by the removal of the chlorine atom from the molecule, leaving behind a positively charged methoxy group.

4. The positively charged methoxy group is then protonated by the hydrogen atom in methanol, resulting in the formation of a new covalent bond between the two molecules.

5. Heat is then applied to the reaction mixture, which increases the reaction rate and facilitates the formation of the desired product, (r)-3-methyl hexane-2-methanol.

This substitution reaction is an example of a nucleophilic substitution reaction, which is a type of chemical reaction in which a nucleophile (a molecule with an electron-rich center) replaces a leaving group (a molecule with an electron-poor center) from a substrate molecule.

Hence A and D are the products of the reaction. The image attached below explains Clearly the reaction.
