Question

1)Deduce the type of crystal structure shown by graphane.

2) State how two carbon atoms form a carbon-carbon bond in graphane.
3)Suggest why graphane does not conduct electricity.
4)Deduce the empirical formula of graphane.

Answer 1

1) Graphane has a face-centered cubic crystal structure. 2) The carbon-carbon bond in graphane is formed through the overlapping of sp3 hybridized orbitals. 3) Graphane does not conduct electricity because it is an insulator. 4) The empirical formula of graphane is CH.

Step-by-step explanation:

1) Graphane has a crystal structure similar to that of diamond, which is a face-centered cubic structure. In this structure, each carbon atom is bonded to four other carbon atoms, forming a tetrahedral arrangement.

2) In graphane, two carbon atoms form a carbon-carbon bond through the overlapping of their sp3 hybridized orbitals. This results in the formation of a sigma bond.

3) Graphane does not conduct electricity because it is an insulator. The electrons in graphane are localized between the carbon atoms and are not free to move, which prevents the flow of electricity.

4) The empirical formula of graphane is CH.
