Is Cl A better nucleophile than Br?
#468 in 1001 in Orgo Chem Examkrackers says that Br- is a better nucleophile than Cl-, but #458 says that Br- is a better leaving group than Cl-. I get that Br- is bigger than Cl- and can therefore better stabilize the negative charge, making it a better leaving group.
Why Iodine is the best leaving group?
Iodine is a better leaving group than other halogen atoms due to its larger size. Due to larger size, charge density decreases and it becomes stable. So, its a better leaving group.
Which is a better leaving group Cl or I?
So the order for increasing basic character is IClbetter leaving group than flouride ion because after the substitution or elimination reaction, the negative charge on the iodide ion will easily be dispersed due to its large size.
