6/20

The formula for Ethylene (Ethene) is C2H4.

7/20

Describe the structure of Graphite.

7/20

In Graphite, each carbon atom is bonded to three others in a plane, forming hexagonal arrays with layers.

8/20

What is the combustion reaction for Methane?

8/20

The combustion of Methane: CH4 + 2O2 → CO2 + 2H2O + heat.

9/20

What kind of compounds are Alkenes?

9/20

Alkenes are unsaturated hydrocarbons that contain at least one double bond.

10/20

What is the main product of burning carbon-containing compounds?

10/20

The main product is carbon dioxide (CO2) along with heat and light.

11/20

Explain the concept of structural isomers.

11/20

Structural isomers are compounds that have the same molecular formula but different structural arrangements.

12/20

What is a functional group?

12/20

A functional group is a specific group of atoms within a molecule that determines its chemical properties.

13/20

What is the general formula for Alkanes?

13/20

The general formula for Alkanes is CnH2n+2.

14/20

Define Oxidation in organic chemistry.

14/20

Oxidation is the process of adding oxygen or removing hydrogen from a compound.

15/20

What is the product of complete combustion of hydrocarbons?

15/20

The complete combustion of hydrocarbons produces carbon dioxide and water.

16/20

How does Carbon's small size affect its bonding?

16/20

Carbon's small size allows its nucleus to hold shared electrons strongly, leading to stable bonds.

17/20

What are Homologous Series?

17/20

Homologous series are groups of compounds with the same functional group and similar chemical properties but different molecular sizes.

18/20

What type of bond exists in Ethyne?

18/20

Ethyne (C2H2) has a triple bond between the two carbon atoms.

19/20

What distinguishes diamond structure from other allotropes of Carbon?

19/20

In diamond, each carbon atom is bonded to four other carbon atoms in a 3D structure.

20/20

Identify the test for confirming the presence of Carbon.
