Question

Boiling point of cis-1-chloroprop-1-ene is ____ than trans-1-chloroprop-1-ene.

Answer 1

(i) (Refer to Image 1) has more boiling point than (ii) (Refer to Image 2)

Cis isomers are more boiling point than that of trans. Polarity is more in cis isomer and boiling point is caused by inter-molecular forces, thereby raising the boiling point. In trans isomer, polarity is less.
