An organic compound on heating with CuO produces CO2 but no water. The organic compound may be:
CCl4+ 2CuO → 2CuCl2 + CO2
Since, the compound on heating with CuO produces CO2which contains carbon. Again, it does not produce water, hence it does not contain hydrogen. SO, the orgnic compound is carbon tetrachloride ( CCl4 ).
Hence, Option D is Correct.
