Carbon tetrachloride was formerly used in fire extinguishers for electrical fires. In the second orbit or L-shell = 4 electrons. Beryllium atom structure. Draw a representation of the Raman spectrum of CCl 4 that includes both the Stokes and anti-Stokes lines. Carbon tetrachloride, also known by many other names (such as tetrachloromethane, also recognised by the IUPAC, carbon tet in the cleaning industry, Halon-104 in firefighting, and Refrigerant-10 in HVACR) is an organic compound with the chemical formula CCl 4.It is a colourless liquid with a "sweet" smell that can be detected at low levels. With these derived atomic orbitals, symmetry labels are deduced with respect to rotation about the principal axis which generates a phase change, pi bond ( π ) [25] or generates no phase change, known as a sigma bond ( σ ). ... the molecule. This work is based on nature and laboratory observations. If you are planning to draw a carbon tetrachloride (CCI4) Lewis structure, you will have to count all the valence electrons involved in each part of the overall molecule.
