The gas evolved when methylamine reacts with nitrous acid is
Answer:
When methylamine reacts with nitrous acid (HNO2), the gas evolved is nitrogen gas (N2). This reaction produces nitrogen gas along with water and other byproducts. Methylamine (CH3NH2) is a primary amine, and when it reacts with nitrous acid, it undergoes a diazotization reaction to form nitrogen gas, which escapes as a gas from the reaction mixture. Nitrous acid is used to convert primary amines like methylamine into diazonium salts, and during this process, nitrogen gas is released. This reaction is commonly employed in the synthesis of various organic compounds and dyes.
