Hydrogen bonds are a type of dipole–dipole interaction. They are formed when a hydrogen atom bonds with a very electronegative atom, such as oxygen or nitrogen. The electronegative element attracts the shared pair of electrons more toward itself, so the hydrogen atom has a slightly positive charge.

- No hydrogen bonding is possible between molecules of propane, resulting in a lower boiling point compared with ethanol Ethanol, C2H5OH, and dimethyl ether, CH3OCH3, have the same molar mass, yet,
Hydrogen bonding occurs in polar molecules containg hydrogen atoms bonded directly to small electronegative atoms (flourine (F), nitrogen (N) and oxygen (O). Now that you know the criteria for hydrogen bonding you can eliminate choices A and D because these molecules has H but does not contain F, N or O.
- Hydrogen Bonding: A special case of dipole-dipole where a covalent bond occurs between a hydrogen of one molecule and a Oxygen, Nitrogen or Fluorine of a different molecule. However, if this molecule came across a molecule such as HF there would be hydrogen bonding because the Hydrogen of Acetone would form a bond with the Flourine of HF.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

- - hydrogen bond donors - hydrogen bond acceptors H-bonding is especially strong in water because: 1. the O—H bond is very polar 2. there are 2 lone pairs on the O atom 3. Each H 2O molecule can form four H bonds to other molecules, resulting in a tetrahedral arrangement. hydrogen bond donor hydrogen bond acceptor
Apr 27, 2012 · Aprotic solvents may have hydrogens on them somewhere, but they lack O-H or N-H bonds, and therefore cannot hydrogen bond with themselves. For the average first semester student, these distinctions come up the most in substitution reactions, where hydrogen bonding solvents tend to decrease the reactivity of nucleophiles; polar aprotic solvents ...
