Which of the following is soluble in water?

• (A) CS₂
• (B) C₂H₅OH
• (C) CCl₄
• (D) CHCl₃

To determine which of the given compounds is soluble in water, let's look at each option:

Options Analysis

• CS₂ (Carbon Disulfide): This compound is nonpolar and does not mix well with water, making it insoluble.
• C₂H₅OH (Ethanol): Ethanol is polar due to its hydroxyl (-OH) group, allowing it to dissolve easily in water.
• CCl₄ (Carbon Tetrachloride): This is a nonpolar solvent and is also insoluble in water.
• CHCl₃ (Chloroform): While somewhat polar, chloroform is not significantly soluble in water.

Conclusion

The only compound that is soluble in water from the options provided is C₂H₅OH (Ethanol).
