How to draw structure of a compound

• Can we write the structure of a compound if the name of the compound is given?
  Yes, we can write the structures from the name of the compound as follows:

1. From the word root in the name write the carbon atoms in the main chain
2. Select counting of carbon atoms in the appropriate manner from left to right or right to left as for the name given.
3. Attach the substituents to respective carbon atoms as per their numbers and numerical designations.
4. Find the functional group if any from the name of the compound see that it is correctly arranged in the structure.
5. Keeping in view that the tetravalency of each carbon atom has to be satisfied use hydrogen atoms in the required number and complete the structure.

Examples:

1. 2–methyl pentan–3–ol
2. 2–bromo–3–ethyl penta–1, 4–diene
3. 3–bromo–2–chloro–5–oxohexanoic acid
4. 3–amino–2–bromo hexan–1–ol
5. 3, 4–dichloro but–1–ene
