Question

Tertiary haloalkanes are practically inert to substitution by SN2 mechanism because of

Answer 1

In SN2 reaction unlike SN1 reaction no carbocation is formed.

Instead the nucleophile attacks from behind the molecule.

Tertiary haloalkanes are bulky and Well protected from all sides.

This does not allow attack of nucleophile .

This is known as Steric Hinderance.

This makes haloalkanes inert to substitution by SN2

Answer 2

Explanation:

this is due to the movement of water particles. due to this, the copper sulphate particles and water molecules get mix with each other by the process of diffusion. due to this diffusion, when a crystal of copper sulphate is placed at the bottom of a beaker containing water , the water slowly turns blue.
