The covalent compound SCl2 is named sulfur dichloride.
In this compound, sulfur (S) is the central atom bonded to two chlorine (Cl) atoms. The prefix ‘di-‘ in ‘dichloride’ indicates that there are two chlorine atoms present. Sulfur is in group 16 of the periodic table and typically forms two single bonds to achieve a stable electron configuration.
When naming covalent compounds, we use prefixes to denote the number of atoms of each element involved. For sulfur, we do not use a prefix since there is only one sulfur atom in the molecule. Hence, we simply say ‘sulfur’ followed by the prefix ‘di-‘ for chlorine, resulting in sulfur dichloride.
