Question

b) ch3 - ch_ oh - ch socl2___/ pyridine ​

Answer 1

Explanation:

When Propan-2-ol reacts with Thinoyl chloride in the presence of pyridine then it produce 2-chloro propane and Sulphur dioxide and Hydrochloric gas is released.

Chemical equation :-

CH3-CH(OH)-CH3 + SOCl2 → CH3-CH(Cl)-CH3 + SO2 + HCl

Additional information :-

Markovnikov's rule :-

→ Markovnikov's rule say that hydrogen is attached where hydrogen is more and halogen is attached where hydrogen is less.

Anti-Markovnikov's rule :-

→ Anti-Markovnikov's rule say that hydrogen is attached where hydrogen is less and halogen is attached where hydrogen is more.

→ Anti-Markovnikov's rule is also known as Kharasch's effect or peroxide effect.

Finkelstein reaction :-

→ Alkyl iodide are often prepared by the reaction of alkyl chloride/bromide with NaI in dry acetone. This reaction is known as Finkelstein reaction.

Sandmeyer's reaction :-

→ The diazonium salt is prepared by treating aniline dissolved in cold aqueous mineral acid with an aqueous solution of sodium nitrite at low temperature (0-5°C).

→ Bromo and chloroarenes can be prepared by treating a freshly prepared diazonium salt solution with cuprous bromide or cuprous chloride.

By the action of Thinoyl chloride :-

→ Chloroalkane is prepared by refluxing the alcohols with SOCl2 in the presence of pyridine.

→ Best method for preparation of Chloroalkane.
