A B and C are...

Question

A B and C are three substances.A does not conduct electricity in the solid or liquid state.B conducts electricity both in the fused and solution C conduct electricity in aqueous solution but not in liquid state.which of the following statements is false regarding A B and C

A) A has polar covalent linkage

B) a has nonpolar covalent linkage

C) B is ionic in nature

D) C has polar covalent linkage

Open in App

Solution

A polar covalent molecule may conduct electricity in liquid state due to formation of ions. For example HCl will dissociate a little in liquid state as under
HCl->H+ + Cl-
So as A does not conduct electricity in solid as well as liquid state it should be pure covalent So option A is wrong

Q. Two substances

X

Y

are dissolved in water under suitable conditions.

X

Y

is a solid under normal conditions. Solution of

Y

is found to conduct electricity but not

X

. Based on the conclusion, identify the nature of bond present in

X

Y

with appropriate reasons as given below.

Arrange the step given below in a sequence:
(a)

Y

is a solid at room temperature and its aqueous solution conducts electricity. This shows that it is an ionic compound.
(b)

X

on dissolution in water doesn't conduct electricity and is a gas at room temperature. Hence it should be a nonpolar covalent molecule.
(c) Aqueous solutions of both ionic compounds and polar covalent compounds conduct electricity because of the presence of free ions.
(d) All ionic compounds are solids and more of the nonpolar covalent molecules are gases or solids at room temperature. Polar covalent compounds are liquids or gases.
