What is the structure of pentane

Pentane is an alkane with the molecular formula C₅H₁₂. It consists of a straight chain of five carbon atoms (C) connected by single bonds. Each carbon atom is bonded to enough hydrogen atoms (H) to satisfy the tetravalency of carbon, meaning each carbon forms four bonds.

The structure can be represented as follows:

C - C - C - C - C

Each carbon (C) is connected to hydrogen (H) atoms. The structural formula can be written as:

CH₃ - CH₂ - CH₂ - CH₂ - CH₃

This shows that the terminal carbon atoms are bonded to three hydrogen atoms each, while the internal carbon atoms are bonded to two hydrogen atoms each.

Pentane can also exist in branched forms, such as isopentane (2-methylbutane) and neopentane (2,2-dimethylpropane), but the straight-chain form is the simplest representation.
