0.44g of a monohydric alcohol liberates 112 cm of methane.
Mass of monohydric alcohol which gives 22400 cm3 of methane = \(\frac{22400\times0.44}{112}\) = 88
C5H12O molecular fórmula has mass number 88 and it shows eight possible isomers. But neopentyl alcohol reacts with PCC to form neopentyl aldehyde, which shows positive silver mirror test. Therefore, compound is. neopentyl alcohol (or) 2, 2 – dimethyl propan – l – ol.
