A popular method of synthesizing them involves the addition of an alkyl halide to potassium phthalamide.
Both methyl orange and methyl red contain a diazo bridge para to one of these functional groups. Benzenesulfonyl chloride is used in a chemical test to detect this functional group named for Hinsburg, and a method of removing this functional group involves adding excess methyl iodide and heat. A popular method of synthesizing them involves the addition of an alkyl halide to potassium phthalamide. Adding one of them to formaldehyde is the first step of the Mannich reaction, and the previous reactions are the Hofmann elimination and Gabriel synthesis. Quaternary ones carry a positive charge, and aniline is a simple aromatic one. Primary, secondary, and tertiary ones have a lone pair. For 10 points, name this functional group which contains a nitrogen atom single bonded to carbon chains.
