WebMar 13, 2024 · The CH4 molecule will have 109.5° bond angles as there is no distortion in its shape. Generally, the lone pairs in the molecule distort the shape of the molecule, which changes the molecule’s bond angles. But as there are no lone pairs of electrons in this molecule, H-C-H’s bond angle is 109.5°. 1,2-Dichloroethene, commonly called 1,2-dichloroethylene or 1,2-DCE, is the name for a pair of organochlorine compounds with the molecular formula C2H2Cl2. They are both colorless liquids with a sweet odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2 … See more cis-DCE, the Z isomer, is obtainable by the controlled chlorination of acetylene: C2H2 + Cl2 → C2H2Cl2 Industrially both isomers arise as byproducts of the production of vinyl chloride, … See more The dichloroethylene isomers occur in some polluted waters and soils.
