Vedclass · Answer

(A) . Option $A$ is correct. Power alcohol is a mixture of petrol and ethyl alcohol (usually $10-25\%$ ethanol) used as fuel.
$B$. Option $B$ is incorrect. Rectified spirit ($95.6\%$ ethanol and $4.4\%$ water) is an azeotrope with a boiling point of $78.15^{\circ}C$,which is lower than both pure ethanol $(78.37^{\circ}C)$ and water $(100^{\circ}C)$.
$C$. Option $C$ is incorrect. $tert	ext{-butyl alcohol}$ is more soluble in water than $isobutyl 	ext{ alcohol}$ due to its more compact structure and greater branching,which reduces the hydrophobic effect.
$D$. Option $D$ is incorrect. Diastase converts starch into maltose,while Zymase is the enzyme used to convert glucose into ethyl alcohol.
