For the equilibrium (axial conformer equatorial conformer of a monosubstituted cyclohexane), the axial conformer is MOST populated when the substituent is :
Options:
Answer:
A
Solution:
The axial population is largest for the substituent with the smallest A-value (the smallest axial penalty). Among the halogens the A-values are roughly F 1.5, 2.2, 2.4, I 2.2 kJ/mol : fluorine pays the smallest price for being axial, so its axial conformer is the most populated.
