Base Write the mechanism for the reaction between 2, 2-dimethy l-3-pentanol and hydrogen bromide. Show how you would make 2-hexanol from acetylene.

Explanation / Answer

Ans 5. c. The relative stability of 2 possible cation intermediates .

The reaction involves formation of two products out of which the compound that has halogen on the more substituted carbon is the major organic product and the compound with halogen atom on the less substituted carbon is the minor organic product.
