Question

In unsaturated compounds, what is the minimum number of carbon atoms and why?​

Answer 1

Answer:

2 carbon atoms because double or triple bond is formed between at least 2 carbon atoms

Answer 2

Unsaturated compounds (hydrocarbons) contain at least two carbon atoms

• Unsaturated compounds are those types of compounds that have the presence of unsaturation in them.
• By unsaturation, we mean the presence of a double or triple bond between at least two C atoms.
• Unsaturated compounds (hydrocarbons) can consist of long chains, aromatic compounds, short chains, etc, there exists, a huge variety of unsaturated compounds.
• Unsaturated compounds have a lower melting and boiling point than saturated compounds due to the presence of a double or triple bond in between them.
• Some examples of unsaturated compounds include oils, ethene, ethyne, etc.

Thus, unsaturated compounds need at least 2 carbon atoms with either a double or triple bond between them to be classified as unsaturated.
