Which of the following alcohols does not give an iodoform test?

2-butanol alcohols does not give an iodoform test.

A yellow precipitate of iodoform is produced because butanol also includes the chemical group ${\mathrm{CH}}_3\mathrm{CH}\left(\mathrm{OH}\right)$. Iodoform testing is only performed on ethanol, primary alcohol. Alpha methyl groups are not present in it. The reaction of the provided chemical with NaOH and $ I 2$ does not produce an iodoform.

Hence, option is correct.
