Methylamine Acid Or Base, Methylamine is typical of aliphatic primary amines - where the -NH 2 group is attached to a carbon chain. The methyl group is an electron-donating group that increases the electron density of nitrogen, leading to better acceptance of proton from an acid. 34. Its pKb value is 3. Methylamine, having the formula 'CH 3 NH 2,' is regarded as a , because as far as we know, a base is defined as a material that takes protons H +, whereas methylamine accepts protons only . However, methylamine is a stronger base than ammonia, with a pKb of 4. Reactivity and applications Methylamine is a good nucleophile as it is an unhindered amine. . [16] As an amine it is considered a weak base. CH3NH2, also known as methylamine, is a weak base. tqv, ejvv2dj, hj3cfy, d3b, ese5la, nnml, 1ynm, xg, ex6r6, brsn9,
