Question

Determine if each pair of compounds forms a homogenous solution when combined. For those that form homogenous soulutions, indidcate the type of forces that are involved.

a) CH3CH2CH2CH2CH3 and CH3CH2CH2CH2CH2CH3 b) CBr4 and H2O c) LiNO3 and H20 d) CH3OH and CH3CH2CH2CH2 CH3

Answer 1

CH3CH2CH2CH2CH3 and CH3CH2CH2CH2CH2CH3

Both are non-polar molecules. So, they form homogenous solution. London dispersion forces are present.

-----------------------------------------------------------

b) CBr4 and H2O

CBr4 is non-polar compound and H2O is polar compound. So, they do not

form homogenous solution.

-------------------------------------------------------------------------

c) LiNO3 and H20

LiNO3 isionic compound and H20 is polar compound. So, they form homogenous solution..

Ionic forces are present.

--------------------------------------------------------------------------------

d) CH3OH and CH3CH2CH2CH2 CH3

CH3OH is polar compound and CH3CH2CH2CH2 CH3 is non-polar compound.

So, they do not form homogenous solution.
