Answer 1

The correct answer is CnH2n+2.

Key Points

Alkanes are a class of hydrocarbons that consist of only single bonds between carbon atoms.
The general formula for alkanes is CnH2n+2, where n represents the number of carbon atoms.
Alkanes are also known as paraffins and are saturated hydrocarbons.
They are the simplest type of hydrocarbon and are typically found in natural gas and petroleum.
Examples of alkanes include methane (CH4), ethane (C2H6), and propane (C3H8).
Alkanes are used as fuels and lubricants due to their properties.

Additional Information

C2nH2n
- This formula does not correspond to any common class of hydrocarbons.
CnHn
- This formula does not align with any known hydrocarbons.
CnH2n
- This formula represents the general formula for alkenes, which are unsaturated hydrocarbons containing at least one carbon-carbon double bond.
