Trans-2-Butene has higher melting point than cis-2-Butene. Why? |
| Answer» Trans-2-butene has higher melting point than cis isomer because mp depends on packing efficiency. Trans molecule have effective packing than cis-molecule as it is more symmetric. Cis molecule has less effective packing and replusion also exists between the bulky methyl groups which are on the same side, therefore less melting point. | |
