1. Asplenia is most often observed in patients with right atrial isomerism . 2. Polysplenia results in 90 % of patients with left atrial isomerism . 3. It is an example of a cycloalkene which exhibits geometric isomerism . 4. Biliary atresia is not usually observed in patients with right atrial isomerism . 5. Both exhibit optical isomerism and alphaprodine and betaprodine are racemates. 6. Alfred Werner studied the nitro nitrito isomerism ( 1 and 2 ) extensively. 7. Unlike its derivative prodine, it was not reported to exhibit optical isomerism . 8. Right atrial isomerism is named for its discoverer, Swedish pathologist Bi�rn Ivemark. 9. No example of bond stretch isomerism has been established. 10. Nitro-nitrito isomerism is common, where the nitrito form is usually less stable.
