Molecular Structure
Structural Formula, Measurements show that unknown compound x has the following composition
Based on the empirical formula, the structural formula of compound X can be determined. The simplest molecular formula for a compound with the empirical formula CH2 is CH4. This formula represents a molecule with one carbon atom bonded to four hydrogen atoms.
Molecular Weight
The molecular weight of compound X can be calculated by adding the atomic masses of the constituent atoms. For CH4, the molecular weight is:
“`Molecular weight = (12.01 g/mol) + (4 x 1.01 g/mol) = 16.05 g/mol“`
Molecular Geometry and Bonding
The molecular geometry of CH4 is tetrahedral. This geometry results from the hybridization of the carbon atom’s valence orbitals. The carbon atom has four valence electrons, which hybridize to form four equivalent sp3 orbitals. These orbitals are arranged in a tetrahedral shape, with the hydrogen atoms occupying the four corners of the tetrahedron.
Physical Properties
Physical Description
Compound X (CH4) is a colorless, odorless gas at room temperature and pressure. It is lighter than air and has a density of 0.717 g/L at 0 °C.
