Abstract
Students completing a year-long organic chemistry sequence were interviewed to assess how they understood, explained, and applied knowledge of hydrogen bonding to the physical behavior of molecules. Students were asked to define hydrogen bonding and explain situations in which hydrogen bonding could occur. They were asked to predict and explain how hydrogen bonding influences boiling point, the solubility of molecules, and NMR and IR spectra. Results suggest that although students may be able to give appropriate definitions of hydrogen bonding and may recognize when this phenomenon can occur, significant numbers cannot apply their knowledge of hydrogen bonding to physical properties of molecules or to the interpretation of spectral data. Some possess misconceptions concerning boiling points and the ability of molecules to induce hydrogen bonding. Instructional strategies must be adjusted to address these issues.

A New "Bottom-Up" Framework for Teaching Chemical Bonding
Leeor Kronik , Tami Levy Nahum , Rachel Mamlok-Naaman and Avi HofsteinJournal of Chemical Education2008 85 (12), 1680A New "Bottom-Up" Framework for Teaching Chemical Bonding
Leeor Kronik , Tami Levy Nahum , Rachel Mamlok-Naaman and Avi HofsteinJournal of Chemical Education2008 85 (12), 1680Traditional curriculum for teaching bonding often fosters the use of over-simplifications and over-generalizations. Therefore, there is a need for a presentation that is consistent with current scientific knowledge and that provides the student with the ...
Molecular Handshake: Recognition through Weak Noncovalent Interactions

Parvathi S. MurthyJournal of Chemical Education2006 83 (7), 1010The weak noncovalent interactions between substances, the handshake in the form of electrostatic interactions, van der Waals' interactions or hydrogen bonding is universal to all living and nonliving matter. They significantly influence the molecular and ...

Simple Dynamic Models for Hydrogen Bonding Using Velcro-Polarized Molecular Models
Emeric SchultzJournal of Chemical Education2005 82 (3), 401Simple Dynamic Models for Hydrogen Bonding Using Velcro-Polarized Molecular Models
Emeric SchultzJournal of Chemical Education2005 82 (3), 401This article describes the use of models that dynamically illustrate the unique characteristics of weak intermolecular interactions, specifically hydrogen bonds. The models clearly demonstrate that H-bonds can break and reform while covalent bonds stay ...
