Which carbide does not produce any hydrocarbon when it reacts with water?

1. SiC
2. Be2C
3. CaC2
4. Mg2C3

Correct answer: SiC

Solution

Silicon carbide (SiC) does not produce hydrocarbons when it reacts with water because it does not contain carbon in a form that can form hydrocarbons; instead, it primarily reacts to produce silicon dioxide and hydrogen.
