  • question_answer 59)   The most commonly used reducing agent is : (a)\[AlC{{l}_{3}}\]                            (b)\[PbC{{l}_{2}}\]                           (c)\[SnC{{l}_{4}}_{_{~}}~\]                          (d)\[SnC{{l}_{2}}\]

    Answer:

      (d) Tetravalency of tin is mere stable than divalency. Thus,\[SnC{{l}_{2}}\] acts as a reducing agent. \[SnC{{l}_{2}}+2HgC{{l}_{2}}\xrightarrow{{}}SnC{{l}_{4}}+H{{g}_{2}}C{{l}_{2}}\] \[SnC{{l}_{2}}+H{{g}_{2}}C{{l}_{2}}\xrightarrow{{}}SnC{{l}_{4}}+2Hg\]
