Question

19. Answer any one of the following:

a. The soft crystalline form of carbon is______

c. Why are most carbon compounds poor conductors of electricity?

d. What would be the electron dot structure of carbon dioxide which has the formula C​

Answer 1

Answer:

a.GRAPHITE

c.

Carbon compounds are poor electrical conductors because they form covalent bonds, and they do not give rise to free electrons because all electrons are used to create the covalent bond. Also carbon compound does not dissociate itself into ions, so carbon compounds are poor electrical conductors.

d.Electron dot structures of carbon dioxide:

The carbon is the central atom of this molecule.

Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond.

Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.

Answer 2

Answer:

a. graphite.

c. carbon compounds are poor electrical conductors because they form covalent bonds, and they do not give rise to free electrons because all electrons are used to create the covalent bond.

d. bandai oxide is a gas which is made by the combination of carbon and oxygen element. this has four valence electrons

this as six valence electrons.
