  • question_answer 77)   Find out the oxidation number of chlorine in the following compounds and arrange them in increasing order of oxidation number of chlorine. \[NaCl{{O}_{4}},NaCl{{O}_{3}},NaClO,KCl{{O}_{2}},C{{l}_{2}}{{O}_{7}},Cl{{O}_{3}},C{{l}_{2}}O,\]\[NaCl,C{{l}_{2}},Cl{{O}_{2}}.\] Which oxidation state is not present in any of the above compounds?

    Answer:

      \[\overset{-1}{\mathop{NaCl}}\,,\overset{0}{\mathop{C{{l}_{2}}}}\,\overset{+1}{\mathop{NaClO}}\,,\overset{+1}{\mathop{C{{l}_{2}}O}}\,,\overset{+3}{\mathop{KCl{{O}_{2}}}}\,,\overset{+4}{\mathop{Cl{{O}_{2}}}}\,,\overset{+5}{\mathop{NaCl{{O}_{3}}}}\,,\overset{+6}{\mathop{Cl{{O}_{3}}}}\,,\]\[\overset{+7}{\mathop{NaCl{{O}_{4}}}}\,,\overset{+7}{\mathop{C{{l}_{2}}{{O}_{7}}}}\,,\] (+2) oxidation state is not found in any of these compounds.
