The molar elevation constant is related to the solute's ability to elevate the boiling point of the solvent. This is affected by the solute’s molecular size, structure, and the extent to which the solute molecules interact with the solvent.
1. Step 1: Understand molar elevation constant. - The molar elevation constant depends on the molecular mass and polarity. Larger and non-polar molecules usually have higher constants as they can dissolve better in non-polar solvents.
2. Step 2: Analyze each compound. - CHCl (Chloroform): This is a polar molecule, and while it has a moderate molar elevation constant, it is less than CCl . - CCl (Carbon tetrachloride): CCl is a large, non-polar molecule, which interacts strongly with non-polar solvents. Its molar elevation constant is higher compared to CHCl and CH COOH. - CH COOH (Acetic acid): This molecule is polar, and its molar elevation constant is lower than CCl . Thus, CCl has the highest molar elevation constant.
