Question

$I$. Ethanol ($C_2{H}_{5}OH$) will dissolve in both water ($H_{2}O$) and octane ($C_8{H}_{18}$).
$II$. Ethanol molecules contain both a non-polar region and a polar region.

• A. Statement $I$ is true, Statement $II$ is true
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false

Answer 1

The correct option is C Statement $I$ is false, Statement $II$ is true

Statement I: It is false because ethanol is a polar compound . So water will only be divided in it, not the octane because it is non-polar.

Statement II: It is correct because ethanol contain one part (i.e. OH) and other non-polar part is hydrocarbon chain.
