conformational analysis Flashcards
1
Q
what is conformation?
A
diff 3D arr in space of the atoms in a mol which can be converted into one another just by free rotation about the axis along C-C
2
Q
Rotamers
A
isomers are conformers/R. interconvertible at room temp.
3
Q
non-isoable
A
isomers that cannot be separated
4
Q
total no of conformers or rotamers
A
infinite
5
Q
torsional starin
A
weakrep. interaction caused by small energy barrier b/w adjacent bond
