Final answer:
This question involves determining the molecular geometry and hybridization of carbon atoms in a molecule, a key concept in organic chemistry. Carbon atoms with four single bonds exhibit a tetrahedral geometry with sp³ hybridization, whereas carbon atoms involved in a triple bond have a linear geometry with sp hybridization.
Step-by-step explanation:
The question concerns the geometric configuration and hybridization of carbon atoms in a molecule, which are important concepts in organic chemistry. In general, the geometry of a carbon atom can be tetrahedral, trigonal planar, linear, etc., depending on the number and types of bonds it forms with other atoms.
The hybridization of an atom in a molecule reflects the mixing of its atomic orbitals to form the correct number of equivalent hybrid orbitals that will form covalent bonds with other atoms in the molecule.
For example, a carbon atom with four single bonds is usually sp³ hybridized, meaning it has a tetrahedral geometry with bond angles of approximately 109.5°. In contrast, a carbon atom involved in a triple bond is sp hybridized, leading to a linear geometry with bond angles of 180°.
