Verified step by step guidance

Identify the structure of methane: Methane (CH₄) consists of one carbon atom bonded to four hydrogen atoms.

Understand the concept of polarity: A molecule is non-polar if the distribution of electrons between the atoms is even. Methane is non-polar because the C-H bonds are symmetrically arranged and the electronegativity difference is small.

Define an alkane: Alkanes are hydrocarbons with only single bonds between carbon atoms. Methane, with its single carbon and four hydrogen atoms, is the simplest alkane.

Explain saturated hydrocarbons: A saturated hydrocarbon has only single bonds between carbon atoms, with no double or triple bonds. Methane fits this definition as it has only single bonds.

Clarify the carbonyl group: A carbonyl group consists of a carbon atom double-bonded to an oxygen atom (C=O). Methane does not contain a carbonyl group, making the statement that it does false.
