2HC= CH+50₂ → 4CO₂+2H₂O+Heat When ethyne is burnt in air, it gives a sooty flame. This is due to incomplete combustion caused by limited supply of air. However, if ethyne is burnt with oxygen, it gives a clean flame with temperature 3000°C because of complete combustion. This oxy-acetylene flame isRead more

When ethyne is burnt in air, it gives a sooty flame. This is due to incomplete combustion
caused by limited supply of air. However, if ethyne is burnt with oxygen, it gives a clean
flame with temperature 3000°C because of complete combustion. This oxy-acetylene
flame is used for welding. It is not possible to attain such a high temperature without
mixing oxygen. This is the reason why a mixture of ethyne and air is not used.
The two features of carbon that give rise to a large number of compounds are as follows: (i) Catenation: It is the ability to form bonds with other atoms of carbon. (ii) Tetravalency: With the valency of four, carbon is capable of bonding with four other atoms. For more answers visit to website: httRead more

A homologous series is a series of carbon compounds that have different numbers of carbon atoms but contain the same functional group. For example, methane, ethane, propane, butane, etc. are all part of the alkane homologous series. The general formula of this series is CnH2n+2. Methane CH₄ Ethane CRead more

Methane CH₄
Ethane CH₃CH₃
Propane CH₃CH₂CH₃
Butane CH₃CH₂CH2CH₃
It can be noticed that there is a difference of -CH₂ unit between each successive
compound.
