A tin compound used for electroplating steel has the formula SnCl₂. What is the systematic name of this compound?

Question

Quizplus · Accepted Answer

The formula indicates that the compound contains both tin (Sn) and chlorine (Cl), and the charges on these ions must balance out to give a neutral compound. The presence of the subscripts "_{2" and "}" indicate that the compound also contains an organic portion, but this does not affect the naming of the tin compound. The use of S, U, and B as subscripts is not part of standard chemical nomenclature and does not affect the name. The presence of "Sn" indicates that the tin is not in the +4 oxidation state (which would be "SnCl4"), and since there is only one possible charge on the chlorine ion (Cl^-), the tin must be in the +2 oxidation state. Therefore, the systematic name for this compound is "tin(II) chloride", which corresponds to choice D.
