AIIMS 2019 Chemistry Methanides MCQ Question

The reaction that produces methanides is represented by the equation SiC + H₂O → SiO₂ + CH₄, where silicon carbide (SiC) reacts with water to yield silicon dioxide (SiO₂) and methane (CH₄). This reaction is significant as it demonstrates the conversion of a carbide to a hydrocarbon, specifically methane. The other reactions listed do not yield methanides; for instance, Be₂C and CaC₂ produce different products (Be(OH)₂ and C₂H₂, respectively) that do not include methane. Understanding these reactions highlights the unique behavior of carbides in producing hydrocarbons under specific conditions.
