Question

Which of following statements is/are the not correct?

• A. $II$ is more soluble than $I$ in $H_{2}O$
• B. $II$ is more soluble than $III$ in $H_{2}O$
• C. $II$ is less soluble than $III$ in $H_{2}O$
• D. $III$ is more soluble than $I$ in $H_{2}O$

Answer 1

The correct option is B $II$ is more soluble than $III$ in $H_{2}O$

Among the given compounds, compound (I) is very less soluble in $H_{2}O$ because of large hydrophobic part, i.e. Carbon ring presence.

Compound (II) is less soluble than compound (III) because there is more H-bonding in case of compound (III).

So, statement (B) is not correct.
