Which of these would you expect to be most soluble in cyclohexane(C6H12)?The least soluble? plz explain!?

Question

a)NaCl
b)CH3CH2OH
c)C3H8

Answer 1

A) not soluable because it is polar
B) not soluable because it is polar
C) soluable because they are non-polar

Like disolves like.
Cyclohexane is non-polar (surrounded by hydrogens)

If you were the one that asked about the structural formula for C6H12 before, you did not tell me that it was cyclic.

In that case, then there are no double bonds/ Put your Carbons in a six carbon ring and attach two hydrogens to each one for the structural formula.

Answer 2

C.

When looking at solubility, remember that "like dissolves like." Anything that is Cs and Hs is nonpolar---those are very nonpolar groups. To figure out what would be most soluble in it, you want a molecule that is also nonpolar. C is only Cs and Hs as well, so they will dissolve in each other.

For A, the molecule is an ionic compound. Ionic compouds tend to be polar. As for B, even though there are Cs and Hs, the Oxygen makes it polar. Maybe not a whole heck of a lot polar, but it's definitely more polar than the cyclohexane and the propane. Because like dissolves like, neither A nor B would be good choices to dissolve with C6H12. Therefore, the answer is C.

Answer 3

Cyclohexane is a nonpolar substance, so another nonpolar substance would be most soluble in it. In this case, that substance would be C, C3H8, because it is also nonpolar.

B would be less polar because it contains a polar side.

Answer 4

properly, see for a substance to dissolve in water, the forces in water would desire to be sturdy sufficient to triumph over the forces of the substance. Water's important forces (intermolecular forces) are hydrogen bonding and dipole-dipole interactions. Now, gazing the indexed compounds you have, there's a fashion interior the ability of the atoms (and polyatomic ions) that carry a molecule of the compound at the same time. Smaller and larger expenditures can carry at the same time greater helpful. you will discover that Ca is smaller than Potassium, so the compounds that have potassium are out of the photograph. Now, learn the charges of phosphate to nitrate. Phosphate is a three- and nitrate is a a million-. Now, the charge of the phosphate outweighs that of the nitrate, so there's a greater effective attraction between calcium and phosphate than between calcium and nitrate. So water can greater genuinely separate the Ca(NO3)2 than the Ca3(PO4)2. by employing the way, the rule of thumb of smaller atoms and better expenditures are greater effective is a ideal regulation, however the call of it fairly is slipping my concepts precise now.

Answer 5

Cyclohexane (hydrocarbons) is insoluble in water (it has hydrophobic structure), therefore, soluble in alcohol, ehter, acetone & benzene.
NaCl (salt)--> soluble in water therefore not soluble in cyclohexane.
CH3CH2OH (is a base solution)---> soluble in water too but may have abit of solubility in cyclohexane.
C3H3 is hydrocarbon therefore soluble in cyclohexane.

answer:

NaCl-->CH3CH2OH-->C3H3 (least to most soluble)

Answer 6

c) C3H8 (propane) because it is non-polar and covalently bonded.

a) NaCl is ionic
b) Butanol is somewhat polar, because of the -OH group

Thus c) is most like cyclohexane and will dsissolve best in it.
