Note also that the boiling point for toluene is 111 o C, well above the boiling point of benzene (80 o C). The key ...
WebExplanation: The phenyl group C 6 H 5 must be present with CH 4 N because it is an aromatic molecule. Because it’s a primary amine, the NH 2 group can be separated, leaving CH 2. The compound’s formula is C 6 H 5 CH 2 NH 2, which stands for benzylamine. C 6 H 5 NH 2 is the formula for benzenamine. 7. WebMelting point: 213.0 to 217.0 °C: eigenschappen.
