What is cis and trans isomer? |
| Answer» They are geometrical isomers.<br>\tCis isomers are molecules with the same connectivity of atoms. They further consist of identical side groups usually on the same side. It is most of the time a polar molecule. Due to loosely packed molecules the melting point of cis isomer is comparatively low.\tA trans isomer has molecules with two same atoms but in the opposite side of the double bond. It is nonpolar or less polar molecule. Due to tightly packed molecules the melting point of trans isomer is high. | |
