, Conformational isomers
Stereo isomers that are produced by C-C sigma bond rotation and are often rapidly
interconvert at room temperature.
,Factors responsible
F for stability of conformation
• H-bonding, dipole dipole interaction, Hyper conjugation
, Eclipsed strain
Bonded Electrons
Bonded Electrons very close (Ө =0) ,
causes e-e repulsion
Two atoms/groups interacting
Sterically hindering
steric effect
H-bonding: hydrogen interaction with any
E.N atom( O, N, ..)
