Question

Cyclohexane (C6H12) is a hydrocarbon (a substance containing only carbon and hydrogen) liquid. Which of the following will most likely dissolve in cyclohexane to form a solution?CH2Cl2HINaBrCH3CH2CH2CH2CH3

Answer 1

CH₃CH₂CH₂CH₂CH₃

Step-by-step explanation:

Cyclohexane is a nonpolar compound. There is a rule that states that "like dissolves like" meaning polar is soluble in polar and nonpolar is soluble in nonpolar.

CH₂Cl₂. This compound is polar

HI. This compound is slightly polar (dipole moment = 0.38 D)

NaBr. This compound is ionic (great difference in electronegativity between the atoms).

CH₃CH₂CH₂CH₂CH₃. This compound is nonpolar, and the one that will most likely dissolve cyclohexane.
