Which of the folllowing statements about the solubility of 1- propanol, ch3ch2ch2oh, and ethanethiol, ch3ch2sh, are true?
A) Ethanethiol is more soluble in water because sulfer has agreater electronegativity value than oxygen.
B) Ethanethiol is more soluble in water because it has a lower molecular mass than 1-propanol.
C) 1-propanol is more soluble in water because it has a greater molecular mass than ethanethiol.
D) 1-Propanol is more soluble in water because oxygen has a greater electronegativity value than sulfer.
