Question

The various steps for writing the IUPAC name of a saturated hydrocarbon is given below.
1) Identify the substituent groups if present any.
2) Numbering of carbon atoms in principal chain in which the substituent groups will have the lowest number.
3) Select the longest chain of carbon atoms.
4) Naming of the root word can be predicted from the number of carbon atoms present in the principal chain.
5) Suffix will be -ane and prefix will be named according to the substituents.
Which of the given arrangements describes the correct order?

• A. 3 1 2 4 5
• B. 3 1 5 2 4
• C. 3 2 4 1 5
• D. 1 3 2 4 5

Answer 1

The correct option is A 3 1 2 4 5
