Answer 2

The series of compounds you provided is a progression of hydrocarbons, each with a different molecular formula. Let's break it down:

1. C2H6: This is ethane, an alkane with two carbon atoms and six hydrogen atoms. It consists of a single bond between the two carbon atoms.

2. C2H4: This is ethene, commonly known as ethylene. It is an alkene with two carbon atoms and four hydrogen atoms. It contains a double bond between the two carbon atoms.

3. C2H2: This is ethyne, commonly known as acetylene. It is an alkyne with two carbon atoms and two hydrogen atoms. It contains a triple bond between the two carbon atoms.

4. C6H6: This is benzene, an aromatic hydrocarbon with six carbon atoms and six hydrogen atoms. It is a cyclic compound with alternating single and double bonds between the carbon atoms.

Overall, the series represents a progression from an alkane (ethane) to an alkene (ethylene) to an alkyne (acetylene) and finally to an aromatic compound (benzene).
