Question
Which of the following solids is not an electrical conductor?
(i) MgO(s)
(ii) I2 (s)
(iii) H2O (s)
(i) MgO(s)
(ii) I2 (s)
(iii) H2O (s)
- (i) only
- Low mass
(ii) Only
- (ii) and (iii)
- (iii) only
Hint:
Electric conductors are known to allow electricity to pass through them.
The correct answer is: (ii) and (iii)
- I2 and H2O are not examples of electrical conductors.
- An electric conductor refers to a substance or element that possesses the capability of passing an electric current through it.
- Among the given options, I2 is a nonpolar molecule and acts as an insulator. It means that it is not capable of transferring current through it. On the other hand, H2O is a hydrogen-bonded molecular solid that also acts as an insulator.
