Question

write hydrobromination of 2Metylpropene?define rules followed in this reaction​

Answer 1

Explanation:

When 2-methyl propene reacts with Hydrobromic acid then it forms 2-bromo-2-methyl propane (Markovnikov's addition rule).

Chemical equation -

( Refer to the attachment. )

Additional information -

1. Markovnikov's rule :-

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

⠀⠀2. 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.

⠀⠀3. 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.

⠀⠀4. 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.

⠀⠀5. 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.
