Problem

Which of the following statements is/are correct?

i. Heptane (CH3CH2CH2CH2CH2CH2CH3) is soluble in water.
ii. Methylene fluoride (CH2F2 is soluble in butane (CH3CH2CH2CH3)
iii. Ammonia is soluble in n-propanol (CH3CH2CH2OH)

A. ii only

B. iii only

C. i and ii

D) ii and iii

E. i and iii

Solution

We’re being asked to determine which of the given statements is/are correct. Each given statement talks about the solubility of the given pair of compounds with each other.

soluble → they will mix and will form a homogeneous mixture
insoluble → they will not mix and will form a heterogeneous mixture


We’re going to use the theory “likes” dissolving “likes”  which states that the solvent can only completely dissolve the solute if they share similar polarity

Therefore, a pure solvent with similar polarity can successfully dissolve a solute to create a solution. 


Let's take a look at each given statement.


i. Heptane (CH3CH2CH2CH2CH2CH2CH3) is soluble in water.
