A. Vegetable oil
B. Any polar substance
C. Any ionic substance.
D. None of the above will work.

Answer 1

Answer:

A. Vegetable oil

Explanation:

Solubility is determined by the principle , "like dissolves like" .

i.e. , if a compound is polar then it will dissolve in a polar compound only , and

if a compound is non - polar then it will dissolve in a non - polar compound only .

Hence , from the question ,

A. Vegetable oil is a non polar compound ,

B. Polar compound

C. ionic compound , is a polar compound .

Since , wate is polar in nature , hence it will get dissolved in a only polar compound ,

Therefore ,

Water will not get dissolved in vegetable oil , being it a non - polar compound .
