The configurations at the three chiral centres in the bicyclodecanol given below, are 
(a)1S, 2S, 6R
(b)1S, 2S, 6S
(c)1R, 2S, 6R
(d)1R, 2S, 6R
Answer
Answer: A ✓ checked by 4AB · confidence medium
Explanation
C-1 (OH up, priorities OH > C-2 > CH₂): S; C-2 (angular Me toward viewer, C-1 > C-6 > C-3 > Me): S; C-6 (H away, C-2 > CH₂ of the carbinol ring > other CH₂): R — 1S,2S,6R (a).
