The hydrogen bonding in the liquid state of the given molecular compounds is to be explained. Concept Introduction: When hydrogen forms bond with any other more electronegative atom, this bond is called a hydrogen bond. The hydrogen atoms act as a donor while the lone pair of electrons present in a more electronegative atom acts as an acceptor leading to bond formation. The bond formed is the weak bond and has some covalence in it. It is basically an electrostatic attraction. It can be intermolecular or intramolecular. Mainly hydrogen forms bond with second-row element like nitrogen, oxygen, fluorine etc.

Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2.
