What is the correct name for the molecular compound with the formula SCl_2?
A
sulfur chloride
B
sulfur dichloride
C
disulfur dichloride
D
sulfur(II) chloride
Verified step by step guidance1
Identify the elements present in the compound SCl_2: sulfur (S) and chlorine (Cl).
Determine the number of atoms of each element in the formula: 1 sulfur atom and 2 chlorine atoms.
Recall the naming rules for molecular (covalent) compounds: use prefixes to indicate the number of atoms of each element (mono-, di-, tri-, etc.), except that 'mono-' is often omitted for the first element.
Name the first element (sulfur) without a prefix since there is only one atom, and name the second element (chlorine) with the prefix 'di-' to indicate two atoms, changing 'chlorine' to 'chloride' as per naming conventions.
Combine the names to form the correct name: 'sulfur dichloride'.
