Question

Select the one that has a definite boiling point, True solution Compound Colloid All of these​

Answer 1

Answer:

A “compound” have the fixed boiling point

A “compound” have the fixed boiling pointSince a compound will have definite boiling point where as not in true solution ,colloid because a solution contain a mixture of two compounds and due to presence of two compounds the boiling point may vary and colloidal is an intermediate between the solution suspension forming so definitely both don't have but a compound will have boiling point which is true.

Answer 2

Correct answer is Option (b) that is Compound

The Compound is having a definite boiling point.

A Compound is a substance composed of identical molecules composed of atoms from more than one element.

Explanation:

In the given option-

a) True solution -It is a homogenous mixture of two or more substances in which the particle size of the material is less than the size of 10⁻⁹m.Boiling point may vary.

b)Compound-In compounds molecules are bound together by covalent bonds with a fixed boiling point.

c) Colloid- It is a mixture of one substance dispersed in phase.Boilng point has no role to play in colloids.

d) all of these

Option (b) is the correct answer
