An organic compound on heating with CuO produces \( CO_{2} \) but no water. The organic compound may be
Show Hint
CuO test: Carbon $\rightarrow CO_2$; Hydrogen $\rightarrow H_2O$.

- carbon tetrachloride
- chloroform
- methane
- ethyl iodide
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: $CO_2$ Presence
Production of $CO_{2}$ indicates the presence of carbon in the compound.
Step 2: Absence of Water
Lack of water ($H_{2}O$) production indicates the compound contains no hydrogen.
Step 3: Identification
Among the options, carbon tetrachloride ($CCl_{4}$) contains carbon but no hydrogen. Chloroform ($CHCl_{3}$), methane ($CH_{4}$), and ethyl iodide ($C_{2}H_{5}I$) all contain hydrogen.
Final Answer: (a)
Production of $CO_{2}$ indicates the presence of carbon in the compound.
Step 2: Absence of Water
Lack of water ($H_{2}O$) production indicates the compound contains no hydrogen.
Step 3: Identification
Among the options, carbon tetrachloride ($CCl_{4}$) contains carbon but no hydrogen. Chloroform ($CHCl_{3}$), methane ($CH_{4}$), and ethyl iodide ($C_{2}H_{5}I$) all contain hydrogen.
Final Answer: (a)
