In an alkyl halide, the halogen serves 2 functions
that render the alkyl halide reactive towards
substitution and elimination processes. One is
that halgens serve as leaving groups and
substitution/elimination
reactions can only occur
when a leaving group is present. What is the other
reason?
The halogens have pką values above
zero, making them weaker acids and
more likely to participate in dissolution.
The halogen repels electron density
rendering the adjacent carbon atom
nucleophilic and therefore subject to
attack by an electrophile.
The halogen is usually in an allylic
postion and therefore does not
participate in resonance, making it less
stable and more likely to react.
The halogen withdraws electron
density rendering the adjacent carbon
atom electrophilic and therefore
subject to attack by a nucleophile.

The R groups on adjacent amino acids are on opposite sides of the extended peptide chain, adding to the rigidity. The double bond between carbon and oxygen restricts free rotation. The bond between hydrogen and nitrogen restricts free rotation. The partially double bonded character of the resonance structure restricts free rotation.
