The correct answer is option (B): CH3-OH
Methylamine has the formula CH3NH2.as per the Schmidt reaction it can react with HNO2 to form methanol and nitrogen gas as a by-product. CH₃NH₂+ HNO₂→ CH₃OH+ N₂ +H₂O The nitrous acid will generate an electrophile. This reaction is used for the conversion of amines into alcohol.
