Current Question (ID: 17606)

Question:

$\text{Among the two isomers given above, the reason behind higher boiling point of one isomer as compared to the order is:}$

Options:

1. $\text{Cis - less polar than trans}$
2. $\text{Trans - more polar than cis}$
3. $\text{Cis - more intermolecular forces}$
4. $\text{Trans - more dipole-dipole interactions}$

Solution:

$\text{Hint: The boiling point depends on the force of interaction between the molecules.}$ $\text{Step 1:}$ $\text{Geometrical isomers of Pent-2-ene are given below:}$ $\text{Step 2:}$ $\text{The dipole moment of cis-compound is a sum of the dipole moments of}$ \ C - \text{CH}_3 \ \text{and} \ C - \text{CH}_2\text{CH}_3 \ \text{bonds acting in the same direction.}$ $\text{The dipole moment of trans-compound is the resultant of the dipole moments}$ \ C - \text{CH}_3 \ \text{and} \ C - \text{CH}_2\text{CH}_3 \ \text{of bonds acting in opposite directions.}$ $\text{Hence, cis-isomer is more polar than trans-isomer. The higher the polarity, the greater is the intermolecular dipole-dipole interaction and the higher will be the boiling point. Hence, cis-isomer will have a higher boiling point than trans-isomer.}$
