Question

unlike ionic or covalent bonding, where electrons are transferred or shared, hydrogen bonding is simply the electrostatic attraction between two molecules that have a hydrogen (h) atom covalently bound to a highly electronegative atom (specifically, n, f, or o). remember that hydrogen bonds arent really bonds; theyre simply a special category of dipole - dipole forces.
its important to note that hydrogen bonding can also occur within single large and complex molecules like proteins. in this lesson, however, we will be focusing on smaller molecules, such as water, pictured to the right.
select the best description of hydrogen bonds below:
there are attractions between two or more small, simple molecules
electrons are shared in hydrogen bonds
electrons are transferred in hydrogen bonds

Explanation:

Hydrogen bonding is an electrostatic attraction between molecules. It's not a true bond (electrons aren't shared or transferred like in covalent or ionic bonds). The text mentions it can occur in large molecules (but the focus is on small ones here). The first option aligns with the description of hydrogen bonds as attractions between molecules (even if the text also notes larger - molecule cases, the focus on small ones makes this the best fit among the given options). The second option (electrons shared) is for covalent bonds. The third (electrons transferred) is for ionic bonds.

Answer:

There are attractions between two or more small, simple molecules
