The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Correct IUPAC name for LiSCN: Lithium thiocyanate<\/strong><\/p>\n\n\n\n

\n\n\n\n

Explanation<\/strong><\/h3>\n\n\n\n

LiSCN is an inorganic compound composed of lithium (Li\u207a) as a cation and the thiocyanate ion (SCN\u207b) as an anion.<\/p>\n\n\n\n

To determine its IUPAC name, we break it down:<\/p>\n\n\n\n

    \n
  1. Cation: Lithium (Li\u207a)<\/strong>\n
      \n
    • Lithium is an alkali metal found in Group 1 of the periodic table.<\/li>\n\n\n\n
    • It forms a +1 charge and is named simply as “lithium” in ionic compounds.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Anion: Thiocyanate (SCN\u207b)<\/strong>\n
        \n
      • The SCN\u207b ion is called thiocyanate<\/strong>, a pseudohalide ion.<\/li>\n\n\n\n
      • It consists of a sulfur (S), carbon (C), and nitrogen (N) atom.<\/li>\n\n\n\n
      • The structure is often written as S\u2013C\u2261N or N\u2261C\u2013S, and depending on the bonding arrangement, it can exist in two resonance forms: thiocyanate (SCN\u207b)<\/strong> and isothiocyanate (NCS\u207b)<\/strong>. However, in LiSCN, the SCN\u207b acts as thiocyanate<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

        The IUPAC naming convention for simple ionic compounds is:
        [Name of cation] [Name of anion]<\/strong><\/p>\n\n\n\n

        Therefore, the compound LiSCN<\/strong> is named lithium thiocyanate<\/strong>.<\/p>\n\n\n\n

        \n\n\n\n

        Why not other options?<\/strong><\/h3>\n\n\n\n
          \n
        • The compound contains no prefixes<\/strong> like hexa, tetra, or mono because these are only used for covalent (non-metal + non-metal) compounds, not ionic ones.<\/li>\n\n\n\n
        • It does not<\/strong> contain multiple elements requiring prefixes like “di-” or “tri-.”<\/li>\n\n\n\n
        • It is not an acid<\/strong>, so naming conventions like “thiosulfate acid” or “hydrate” do not apply.<\/li>\n\n\n\n
        • It does not<\/strong> contain “sulfide,” “cyanide,” “nitride,” “carbide,” or “thiosulfate” individually, but rather the specific polyatomic ion thiocyanate<\/strong>.<\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

          Conclusion:<\/strong>
          The correct IUPAC name of LiSCN<\/strong> is lithium thiocyanate<\/strong>.<\/p>\n\n\n\n
