Question

What is the IUPAC name of the given compound?

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

Answer 1

$C{H}_3$

$H_3\stackrel{5}{C}-\underset{|}{\stackrel{4}{C}H}-\underset{|}{\stackrel{3}{C}H}-\stackrel{2}{}\underset{|}{\stackrel{|}{C}}-\stackrel{1}{C}{H}_3$

$C{H}_3$ $OH$ $C{H}_3$

• Consider longest chain and that should contain $OH$ group.
  
• Number such that $OH$ group get low number and here if we count any side, $OH$ is at $3^{rd}$ position. Then number in a way such that sum of positions of other groups will be low.
• At $2^{nd}$ carbon, $2$ methyl groups, at $4^{th}$ carbon, $1$ methyl group is there.
• IUPAC name is $2,2,4-trimethyl-pentan-3-ol$.
