Question

$C{H}_3-\underset{C{H}_3}{\underset{|}{C}H}-\underset{OH}{\underset{|}{C}H}-\underset{C{H}_3}{\underset{|}{\stackrel{C{H}_3}{\stackrel{|}{C}}}-}C{H}_3$

The IUPAC name of the above given compound is:

• A. 2,2,4-Trimethylpentan-3-ol
• B. 2,4,4-trimethylpentan-3-ol
• C. 2-methyl-1-(2-methylpronyl)-propanol
• D. none of the above

Answer 1

The correct option is A 2,2,4-Trimethylpentan-3-ol

$\stackrel{5}{C}{H}_3-\underset{C{H}_3}{\underset{|}{C}\stackrel{4}{H}}-\underset{OH}{\underset{|}{\stackrel{3}{C}}H}-\underset{C{H}_3}{\underset{|}{\stackrel{C{H}_3}{\stackrel{2|}{C}}}-}\stackrel{1}{C}{H}_3$

The compound has 2 methyl groups at carbon number 2 and one methyl group at carbon number 4.

Functional group $-OH$ (ol) is attached at carbon number 3

So its name is 2, 2, 4-Trimethylpentan-3-ol.

Option A is correct.
