alleryAcross all conformations, what stays the same?
ABond amounts and lengths
BBond amounts and letters
CBond angles and lengths
DBond angles and letters
Answer & Solution
Correct answer: C. Bond angles and lengths
1. Rotation does not stretch or bend any bond.
2. Only the relative positions change.
3. In all the conformations, the bond angles and the bond lengths remain the same.
4. So the answer is bond angles and lengths.
