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

Incorrect statement regarding aromaticity is-

1. Compound should have a planar structure.

2. The π–electrons of the compound are completely delocalized in the ring.

3. The total number of π–electrons present in the ring should be equal to (4n + 2) $\mathrm{\pi } \mathrm{electron}$, where n = 0, 1, 2 … etc. This is known as Huckel’s rule. 

4. Compound should have a linear structure
