Add one or more curved arrows to show the movement of electrons in the reaction. To draw the arrows, select More in the drawing menu, then select the appropriate curved arrow. Click on a bond or electron to start a curved arrow. Do not start from an atom. Use the select tool to move the arrow head and tail to the desired placement. When the curved arrow changes from red to black, your arrow has an appropriate starting and ending point. Draw curved arrows. Select Draw Rings More Erase С 0 heat -=-=- H3C—0. +.0—CH HCO CH, 2

H3C - O - O - CH -HCOCH2.

Explanation:

Before chemical reaction can occur, some steps has to be followed in order to give the final product (s), this steps can be shown by drawing the chemical compound and showing how bonds are being broken or formed. Showing this in a stepwise manner is known as reaction mechanism.

From the question above, it is given that the products after heating the reactant gives H3C—0. +.0—CH HCO CH2.

The starting material can be deduce as;

H3C - O - O - CH -HCOCH2.

Heat causes something to divide or melt. Kindly check the attached picture which shows how the deduced starting compound splits to give H3C—0. and .0—CH HCO CH2.
