Phosphine melting point

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. WebComparing the melting points of benzene and toluene, you can see that the extra methyl group on toluene disrupts the molecule's ability to stack, thus decreasing the cumulative strength of intermolecular London dispersion forces. Note also that the boiling point for toluene is 111 o C, well above the boiling point of benzene (80 o C). The key ...
