Homework Answers
(a) The lone pairs of electrons on Nitrogen atoms in the molecules can be donated to Lewis acids which make the molecules suitable Lewis bases.
(b) H- bond is the bonding interaction between an electronegative element in a molecule ( Like O, N, S or halogen) and a H atom attached to an electrinegative element in the same or different molecule.
(c) The drug should have potential to break the covalent bond between two DNA strands. So, the drug should be a strong nucleophile that attachs to a DNA strand breaking the covalent bond between the strands.

Exercise 23.6 The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The figure shows the thymine- adenine bond. Each charge shown is te and the H N distance is 0.110 nm. (Figure 1) Figure 1 of 1 > k 0.280 Onm Thymine Adenine k 0300 N) Part B Compare this energy with the...

The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The figure (Figure 1) shows the thymine-adenine bond. Each charge shown is ±e, and the H−N distance is 0.110 nm.A) Calculate the net force that thymine exerts on adenine. To keep the calculations fairly simple, yet reasonable, consider only the forces due to the...
