In my exam, my teacher asked me if the following is true: "The chair cyclohexane has more axial hydrogens" I did not have time to think, so I just put false. And apparently I was right.
What's the complete question? The chair form has more axial hydrogens than what other form? If the test were referring to the other chair conformation, then you are right.
Cyclohexane has 12 hydrogens, and in its two chair conformations, six substituents are axial while the other are equatorial.
Basically, the question is does boat have more axial H's than
The boat conformation doesn't have any true axial positions. I'm not sure what your professor considers to be axial or not, but if we take the flagpole hydrogens to be "axial," then both the chair and the boat should still have the same number of axial substituents.
TRUE OR FALSE: Boat cyclohexane is a slightly higher energy conformer
than chair cyclohexane because: (a).... (a sub question) T OR F
(b).... (a sub question) T OR F (c)chair cyclohexane has more axial
hydrogens. T OR F
Regarding the question now in context the instability of the boat conformation likely has more to do with flagpole-eclipsing interactions rather than the number of hydrogens.
