Q:

Why are hydrocarbons insoluble in water?

Answer

We know that polar substances are soluble in polar solvents and non polar substances are soluble in non-polar solvents only. Here the hydrocarbons are non-polar molecular substances and water is a polar solvent. So water can't dissolve hydrocabons.


 


Hence, as hydrocarbons are non-polar substances, they are insoluble in water as it is a highly polar solvent.

Q:

Is water a Pure substance?

A) TRUE B) FALSE
Answer & Explanation Answer: A) TRUE

Explanation:

True, Water is a Pure substance and not a mixture.


 


We know that, A mixture is when two or more substances combine physically together. You can find that the mixture retains the properties of the original components.


In water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.


 


Therefore, water is not a mixture; it is a compound and it is pure.
