Which of the following statements correctly describes the hybridization of carbon in methane (CH4)?
A
The carbon atom is sp2 hybridized.
B
The carbon atom is sp hybridized.
C
The carbon atom is sp3 hybridized.
D
The carbon atom is not hybridized.
Verified step by step guidance1
Identify the molecular formula of methane, which is CH₄, indicating one carbon atom bonded to four hydrogen atoms.
Understand that hybridization is a concept used to describe the mixing of atomic orbitals to form new hybrid orbitals, which can form sigma bonds with other atoms.
Recognize that in methane, the carbon atom forms four equivalent sigma bonds with hydrogen atoms, requiring four equivalent hybrid orbitals.
Recall that the formation of four equivalent hybrid orbitals from one s orbital and three p orbitals results in sp³ hybridization.
Conclude that the carbon atom in methane is sp³ hybridized, as it forms four sigma bonds using four sp³ hybrid orbitals.
