Question
Chapter 23.16C, Problem 23.45P
Interpretation Introduction
Interpretation: The diagram which shows hydrogen-bonded guanine-cytosine and adenine-thymine pairs are to be drawn and the reason as to why the hydrogen bonds involved in the pairing are particularly strong is to be stated.
Concept introduction: A hydrogen bond is a strong type of bond or electrostatic attraction which mainly occurs when hydrogen atom is bound to a more electronegative atom. It is of two types; intramolecular hydrogen bonding and intermolecular hydrogen bonding.
To determine: The diagram which shows hydrogen-bonded guanine-cytosine and adenine-thymine pairs and the reason as to why the hydrogen bonds involved in the pairing are particularly strong.

Refer to the bar graph below, Explain why the n→π* interactions contributes more to the overall stabilization of the protein than all the other interactions(C-H-O hydrogen bond,π-π interactions, C5 Hydrogen Bonds, Cation-π interactions, Sulfur-arene interactions, Anion-π interactions, Chalcogen bonds, X-H-π interactions) even though n→π* is the weaker interaction.
Explain why that's the case for EACH of the bonds.
I.e
Why n→π* interactions contribute more to the overall stabilization of the protein than C-H-O hydrogen bonds, even though n→π* is the weaker interaction.
Why n→π* interactions contribute more to the overall stabilization of the protein than π-π interactions even though n→π* is the weaker interaction.
Why n→π* interactions contribute more to the overall stabilization of the protein than C5 Hydrogen Bonds, even though n→π* is the weaker interaction.
