How can we satisfy the valency of carbon?

Valency of carbon atom is four . In alkanes carbon form single covalent bond with other carbon atom and with hydrogen atom. for example in ethane CH2CH3 both of carbon atom satisfy it’s four valancy by forming single covalent bond with hydrogen atom and also with itself.

How does carbon bond in alkanes?

Alkanes. Alkanes, or saturated hydrocarbons, contain only single covalent bonds between carbon atoms. Because of the sp3 hybridization, the bond angles in carbon chains are close to 109.5°, giving such chains in an alkane a zigzag shape.

How is Tetravalency of carbon satisfied graphite?

By Arsh. A carbon atom complete its octet only by sharing it’s valence electrons with other atoms. As a result, a carbon atom forms four covalent bonds by sharing valence electrons with other atoms. This is known as tetravalency of carbon (“ tetra means four”).

Which of the following compounds the valencies of all carbon atoms are satisfied by single bonds?

saturated compounds
You will see that the valencies of all the atoms are satisfied by single bonds between them. Such carbon compounds are called saturated compounds. These compounds are normally not very reactive. However, another compound of carbon and hydrogen has the formula C2H4 and is called ethene.

What is the valency of carbon in alkanes alkenes and alkynes?

Assertion : In alkanes, alkenes and alkynes the valency of carbon is always four.

What type of bond is present in alkanes?

single bonds
Alkanes have only single bonds, alkenes contain a carbon-carbon double bond, and alkynes contain a carbon-carbon triple bond.

What is the valency of carbon in graphite?

The valency of carbon is always 4 in all the compounds. The difference lies just in the bonding. In graphite, carbon undergoes sp2 hybridisation. Carbon atom in graphite form three sigma bonds with another three carbons and these sigma bonds are formed by the overlap of three.

What is Tetra valency of carbon?

It means it has 4 electrons in the outermost shell. Carbon obeys the octet rule and forms 4 covalent bonds with other atoms to get a stable electronic configuration. Thus, carbon is tetravalent (It means valency of carbon is 4.) This is called tetravalency of carbon.

Why are hydrocarbons excellent fuels?

Hydrocarbons such as alkanes undergo combustion reactions with oxygen to produce carbon dioxide and water vapour. Alkanes are flammable which makes them excellent fuels.

What is the valency of carbon in organic chemistry?

The valency of carbon is four and one atom of carbon can make four covalent bonds. The branch of organic chemistry deals with the compounds of carbon. The valency of carbon is 4 and it is, therefore, said to be tetravalent Due to the specific properties of the element, Carbon has established its importance among the other elements.

What are alkenes and alkanes?

They are further classified as alkenes (contain at least one carbon-carbon double bond) and alkynes (contain at least one carbon-carbon triple bond) Open chain (aliphatic) saturated hydrocarbons are called alkanes. Due to their little tendency to undergo chemical changes, they are also known as paraffin. Their general formula is C n H 2n + 2.

What is the difference between branched chain alkanes and isoalkanes?

The alkanes in which all the carbon atoms are not in continuous (same) chain are called branched-chain alkanes. The alkanes in which one methyl group is attached to the second carbon atom of the normal chain of carbon atoms are called isoalkanes.

What is the molecular mass of alkane?

The molecular mass of alkane was found to be 142. Find its molecular formula. Let there are n carbon atoms in alkane, its formula is C n H 2n + 2. Molecular mass of alkane = n × 12 + (2n + 2) × 1 = 142
