Question 3 - Past Year - 3 Mark Questions - Chapter 4 Class 10 - Carbon and its Compounds

(a) Why most of the carbon compounds are poor conductor of electricity?

(b) Write the name and structure of a saturated compound in which the carbon atoms are arranged in a ring. Give the number of single bonds present in this compound.

Answer

(a)

For an atom to conduct electricity, free electrons are required.

Carbon has 4 valence electrons and it forms 4 covalent bonds. Since these bonds are formed by sharing of electrons, no free electrons are present to conduct electricity. So, carbon compounds do not conduct electricity.

(b)

Cyclohexane is a saturated cyclic compound i.e. the  ring. Its structure is as follows  

The total number of single bonds in cyclohexane is 18.
