Question

Add curved arrows to the mechanism shown in Problem 6-25 to indicate the electron movement in each step.

Short answer

In the first step of the reaction$\mathbf{\pi }$ bond of alkene abstract hydrogen ion. In the next step, we get the carbocation as an intermediate. In the next step hydrogen atom loss and we resultant alkene as a product.

Step-by-step solution

Movement of electron

In the first step of the reaction$\mathbf{\pi }$ bond of alkene abstract hydrogen ion. In the next step, we get the carbocation as an intermediate. In the next step hydrogen atom loss and we resultant alkene as a product.

Mechanism of the reaction

The mechanism of the reaction is as follows:
