Hydrogen Bonding MDCAT Quiz, this is a type of intermolecular force which arises when hydrogen is bonded to highly electronegative atoms, such as fluorine, oxygen, or nitrogen. These electronegative atoms pull the electron density away from the hydrogen atom, creating a partial positive charge on hydrogen and a partial negative charge on the electronegative atom. The positive hydrogen atom is attracted to the negative region of another electronegative atom, thus forming a hydrogen bond. Though much weaker than covalent or ionic bonds, this has a profound effect on the physical properties of substances.
MDCAT Quiz on Hydrogen Bonding
The MDCAT Quiz on Hydrogen Bonding tests the ability of the students to apply their knowledge of this intermolecular force to varied chemical scenarios. The questions on the quiz are based on the influence hydrogen bonding has on the boiling point, solubility, and structure of molecules. It may also ask students to identify compounds that can hydrogen bond and explain the consequences of such interactions in various substances.
