Chemistry - STEREO ISOMERISM Question with Solution | TestHub
Boiling point of geometrical isomers depend on dipole moment.
Boiling point ∝ Polarity
Melting point ∝ Packing efficiency
Which of the following is correct :
Options:
Answer:
Solution:
Question Explanation:
Identifying the correct statement regarding the physical properties and stability of various stereoisomers.
Concept:
This is based on Geometrical isomerism, Conformational analysis, Melting Point and stability of
cyclodecenes.
Solution:
(1) In 1,2-Chloroethene cis isomer is more stable than trans due to electrostatic force of attraction in cis form.
(2) In conformation (2), the gauche form is more stable than the anti form due to the hydrogen bond.
(3) Trans-isomers generally have a more symmetrical structure than cis-isomers, leading to better crystal lattice packing and a higher melting point.
(4) In cycloalkenes (4), the cis-isomer is more stable for small rings (upto 11 membered).
