Question

hey...pls explain difference between cis isomers and trans isomers

Answer 1

1)
CIS:
Cis isomers are molecules with the same connectivity of atoms. They further consist of identical side groups usually on the same side.

TRANS:
A trans isomer has molecules with two same atoms but in the opposite side of the double bond.

2)
CIS:
It is most of the time a polar molecule.

TRANS:
It is nonpolar or less polar molecule.

3)
CIS:
Due to loosely packed molecules the melting point of cis isomer is comparatively low.

TRANS:
Due to tightly packed molecules the melting point of trans isomer is high.

4)
CIS:
Likewise, due to the presence of strong attraction forces between atoms cis isomers have a high boiling point.

TRANS:
The boiling point is comparatively low for trans isomer as there are no strong attraction forces.

5)
CIS:
Cis isomers have highly soluble in inert solvents.

TRANS:
They are less soluble in inert solvents.

6)
CIS:
These type of isomers have higher acidic strength.

TRANS:
In trans isomers, the protons are not easily released. So it has less acidic strength.
