Current Question (ID: 10843)

Question:

$\text{The IUPAC name of the above mentioned compound is -}$

Options:

1. $\text{3-Methylcyclobut-1-en-2-ol}$
2. $\text{4-Methylcyclobut-2-en-1-ol}$ (Correct)
3. $\text{4-Methylcyclobut-1-en-3-ol}$
4. $\text{2-Methyl cyclobut-3-en-1-ol}$

Solution:

$\text{Hint: Carbon atom containing OH group gets higher priority.}$ $\text{The four carbon atoms ring is a parent chain. The carbon atom containing the OH group gets higher priority and after that the double bond. Numbering must be done in an anticlockwise direction and carbon atom containing the OH group gets the lowest position.}$ $\text{The structure of a compound with numbering is as follows:}$ $\text{A four-membered ring with OH at position 1, double bond between positions 2-3, and CH}_3 \text{ at position 4}$ $\text{At the second position double bond is present, for that en is used as a suffix. At the fourth position, a methyl group is present. The IUPAC name of the compound is 4-methylcyclobut-2-en-1-ol.}$
