  • question_answer Point out the incorrect statement among the following :

    A)  The oxidation state of oxygen is \[+2\] in \[O{{F}_{2}}\].

    B)  Acidic character follows the order \[{{H}_{2}}O<{{H}_{2}}S<{{H}_{2}}Se<{{H}_{2}}Te\].

    C)  The tendency to form multiple bonds increases in moving down the group from sulphur to tellurium (towards C and N)

    D)  Sulphur has a strong tendency to catenae while oxygen shows this tendency to a limited extent.

    Correct Answer: C

    Solution :

     Multiple bonds formation tendency with carbon and nitrogen decreases from sulphur to tellurium. \[C{{S}_{2}}(S=C=S)\] is moderately stable,\[CS{{e}_{2}}(Se=C=Se)\] decomposes readily whereas,\[CT{{e}_{2}}(Te=C=Te)\] does not exist
