Both compounds have an enormous number of possible isomers: Halichondrin B, with 32 stereocenters has 232possible isomers; Eribulin has 19 with 219 isomers (if I have counted correctly, it does not really matter, there are lots of isomers). Remarkable is the fact that only one of these iso...
To solve the problem of drawing all structurally isomeric secondary chlorides with the molecular formula C5H11Cl, we will follow these steps:Step 1: Understand the Definition of Secondary Chlorides Secondary chlorides are those
