The flourine does not leave in any of the substitution reactions because
it is a stronger base than the Iodine or bromine, meaking it a less stable
leaving group. In the other reaction the hydrogen leaves because it is a
acid-base type reaction, not a substituion reaction. The NH2 is a strong
base and it will remove the hydrogen from the molecule.
