WebMay 13, 2015 · Methanol, CH3OH: molar mass = 32 g/mol; boiling point = 65 °C Methylamine, CH3NH2: molar mass = 31 g/mol; boiling point = -6 °C Methanol has strong hydrogen bonds. The strong intermolecular forces give methanol a high boiling point. It is a liquid at room temperature. Methylamine also has hydrogen bonds.
WebApr 21, 2024 · The stronger the electron-withdrawing group, the more deshielded the adjacent protons and higher their ppm value. Now, 1-6 ppm for protons on heteroatoms is a broad range and to recognize these peaks easier, keep in mind that they also appear broader as a result of hydrogen bonding. WebOH bonds. Thus silane depositions on these treated plastics are intrinsically less hydrolytically stable. Generation of multi layer surface networks via trifunctional silanes, or monolayer generation by use of the bis-isopropyl silanes previously discussed, are both good options if long term exposure of the interface to high or low pH is ...
