Combinatorial chemistry is the branch of synthetic organic chemistry. We all remember mathematics classes at school just before the end of the term when we were given silly sums to do: How many ways can five differently colored beads be arranged on a string? (120). Math teachers call these permutation and combination problems; hence, combinatorial chemistry. Question text: "Below is a list of the
