In a compound $$XY$$, if the electronegativity difference between $$X$$ and $$Y$$ is greater than 1.7, then the compound $$XY$$ is soluble in:

Abenzene
Bcarbon tetrachloride
Cwater
Correct Answer
Dcarbon disulfide

Solution

If the electronegativity difference between two elements is greater than 1.7, then the type of bond between the two elements is an ionic bond and the molecule is an ionic molecule. Ionic molecules are soluble in polar compounds. $$H_2O$$ is a polar compound. So, $$XY$$ is soluble in $$H_2O$$. Hence, option C is correct.
