For cyclohexane indicate the changes in the positions of the axial H atoms as you change from conformation chair (A) to boat and from conformation boat (B) to mirrored chair (C). (Mark the axial hydrogen at A with a 0 and indicate its position at B and at C).
Homework Answers
Remember two rules for conformational changes in cyclohexane.
1- During twisting the position of all axial group will become equitorial (only for the carbon centres where twisting is done) and vice versa.
2- The groups which are written on above the plane will remain above and the group which are below the plane will remain below the plane even after twisting.
Here in first image I m just representing the twisting or
rotation to make you understand how chair is converted to boat and
boat is converted to mirrored chair.Here you can see in first
rotation I m just twisting carbon numbered 4,5,6 while in second
rotation I m rotating carbon numbered 1,2,3.
in next image I represented how hydrogens
are sifting their position. Here you can clearly see in first
rotation at carbon no. 4 axial 0 hydrogen above the plane is still
above the plane after twisting but it has changed its position from
axial to equitorial.same is the case with carbon 5 and 6 . But the
position of hydrogens at 1,2,3 remains same . Similarly in second
rotation we are changing hydrogen postion at 1,2,3.
Suggestion- stereochemistry is all about practice try to draw
these figures 3-4 times you will become familiar with drawing
conformations.
