Ethane Ethane can be envisaged as two methyl groups joined by overlapping sporbitals forming the C-C bond. 1.10A H-109.6 H H 1.54A H The C-C bond is 1.54A As mentioned before,because of the free rotation about the C-C bond,ethane exists in many conformations (conformers). near overlap of sigma bon Ch03 Alkanes (landscape) Page 10Ch03 Alkanes (landscape) Page 10 Ethane Ethane can be envisaged as two methyl groups joined by overlapping sp3 orbitals forming the C-C bond. The C-C bond is 1.54Å. As mentioned before, because of the free rotation about the C-C bond, ethane exists in many conformations (conformers)
