D $Let (2 α, α) be the largest interval in which the function f(t)= |t+1| t^ 2 , t 2 , is \_\_\_\_$

Correct answer

D. $Let (2 α, α) be the largest interval in which the function f(t)= |t+1| t^ 2 , t 2 , is \_\_\_\_$

Step-by-step solution

In the first step protonation of alcohol takes place which leads to the formation of carbocation. Ring expansion takes place in the next step. In the given process five membered ring become six membered ring. Now, the carbocation loses proton in the presence of potassium hydroxide to give alkene.

In the reaction given below ' B ' is:
