Question

$I$. A $2M$ solution of urea (${CH}_4{N}_{2}O$) can be prepared by dissolving $1mole$ of urea in $500mL$ of water.
$II$. Urea is a non-polar molecular compound.

• 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 B Statement $I$ is true, Statement $II$ is false

Urea is a polar molecule because the bond between carbon and oxygen has greatest electronegativity difference.

Molarity of Urea $=\frac{\text{No. of molecules of Urea}}{\text{Volume of Solution (in Litres)}}=\frac{1}{0.5L}=2M$

So, statement I is true and II is false.
