Trichloroethylene

Structure:

1. Chemical Formula: C₂HCl₃

2. Molecular Structure: Contains a two-carbon backbone with one double bond. One carbon is bonded to one hydrogen atom and two chlorine atoms; the other carbon is bonded to one chlorine atom and has a double bond with the first carbon.

3. Bonding: Each carbon is sp² hybridized, forming a planar structure.

4. Geometry: Trigonal planar around each carbon due to the presence of a double bond.

Trichloroethylene

Uses:

1. Solvent: Commonly used as an industrial solvent for degreasing metal parts.

2. Chemical Intermediate: Employed in the synthesis of hydrofluorocarbon refrigerants.

3. Extraction: Used in the extraction of organic compounds and as a carrier solvent in chemical synthesis.
