Problem

Acetone (CH₃COCH₃) is a polar aprotic solvent. Equal masses of the following solids are separately stirred into acetone at 25 °C: • potassium bromide, KBr • acetic acid, CH₃COOH • 1-bromopropane, CH₃CH₂CH₂Br • naphthalene, C₁₀H₈ Which option ranks their solubility in acetone from highest to lowest? (a) KBr>acetic acid>1-bromopropane>naphthalene\text{KBr} > \text{acetic acid} > \text{1\text{-}bromopropane} > \text{naphthalene} (b) acetic acid>naphthalene>1-bromopropane>KBr\text{acetic acid} > \text{naphthalene} > \text{1\text{-}bromopropane} > \text{KBr} (c) acetic acid>1-bromopropane>naphthalene>KBr\text{acetic acid} > \text{1\text{-}bromopropane} > \text{naphthalene} > \text{KBr} (d) 1-bromopropane>acetic acid>naphthalene>KBr\text{1\text{-}bromopropane} > \text{acetic acid} > \text{naphthalene} > \text{KBr}
