11you tell me why you think it is not possible.
If two carbons atoms are joined by sigma bonds then how the free rotation of the atoms or groups attached tetrahedally to the carbon atom is possible

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.
