Work Step by Step
For naming alcohol:
1.First, assign number to the C atoms in straight chain.
2. Numbering will be done so that the C attached with OH group gets the minimum number.
3. Find the total no. of C atoms to find out the word root. (for example, if no. of C atom is 8 , the word root is 'oct')
4. If any substituent is present, then the substituent will be written before word root.
5. For alcohol, suffix 'anol' is added to the word root.
Format: (Substituent name)(word root)(suffix).
6. If same substitute present multiple time, then add 'bi', 'tri', 'tetra' etc. accordingly before substituent name.
The assigned numbers to which the substituents and alcohol are attached are written before substituent name and word root respectively.
