Gauche conformation is a staggered conformation, and the name is associated with gauche interactions between methyl or other alkyl groups at a 60-dihedral angle. As a general representation, compare it with the anti conformation where the large groups are at 180o: … Read more
From General Chemistry and earlier chapters of Organic Chemistry, we know that C-C single bonds are formed by a linear overlap of sp3 orbitals. As an example, let’s recall how each carbon in ethane provides one sp3 orbital to form … Read more
Torsional and Steric Strain In the previous post, we talked about the Newman projections where we also covered the relative energies of anti, gauche, and syn conformations. The destabilization of certain conformations is due to Steric or Torsional strain. These two … Read more
In the previous post, we talked about drawing the two conformations of cyclohexane (ring-flip). Remember that conformations are different arrangements of atoms originating as a result of rotation(s) abound a single bond(s). This means that the ring flip is a reversible process … Read more
In the previous two posts, we have talked about drawing the ring-flip of chair conformations and the A value (1,3-diaxial interactions). And we learned that for a given cyclohexane, the axial conformer is less stable than the corresponding equatorial conformer. … Read more
