In the Victor Meyer test, an alcohol is converted to the alkyl iodide, then to the nitroalkane, then treated with HNOX2 and made alkaline. A blue colour is obtained with
A2-methylpropan-1-ol
Bbutan-1-ol
C2-methylpropan-2-ol
Dbutan-2-ol
Answer: D
Secondary alcohols give a pseudonitrole that forms a blue colour in alkali, primary alcohols give a nitrolic acid (red colour), and tertiary alcohols give no colour. Butan-2-ol is the only secondary alcohol listed.
