The presence of carbon in an organic compound can be shown by

A

heating the compound wih sodium

B

heating the compound with cupric oxide

C

heating the compound on bunsen flame

D

heating the compound with magnesium

Text Solution

Verified by Experts

The correct Answer is:
B
Compound when heated with Cuo reduces CuO to Cu and oxidises C to `CO_(2)` which turns lime water milky.
`C+2CuO to 2Cu+CO_(2)`
`CO_(2)+Ca(OH)_(2)to underset(("Milky"))(CaCO_(3))+H_(2)O`
