Among the two isomers given above, the reason behind higher boiling point of one isomer as compared to the order is :
1. Cis - less polar than trans
2. Trans - more polar than cis
3. Cis - more intermolecular forces
4. Trans - more dipole-dipole interactions
The effect of branching on an alkane is:
1. It increases its boiling point
2. It decreases its boiling point
3. It doesn’t change its boiling point
4. None of the above
