Step-by-step solution

Rules for drawing the structure from the name of the compound

• First find the parent chain/group name and draw the number of carbons .

• Identity the functional group from suffix.

• Add the substituents to the carbon atom.

• Add hydrogen atom to balance the valency of carbon.
