3i cant get ur question b555
the free rotation is possible at room temperature itself..
1free rotation iz possible due 2,
i). heaviest e- density in the σ bond exists along an imaginary line along 2 c - nuclei. n aftr rotation dis e- distribution doesn't change, so d bond strength remains constant through out rotation.
ii). 4 free rotation a small torsional barrier of about 12kJ /mol occur, which iz negligible in comparison 2 c-c bond energy, which iz 350kJ/mol.
