Do hydrogen bonds affect the shape of a molecule? and Paseo/Bond Bridges

Do hydrogen bonds affect the shape of a molecule?



Are hydrogen bonds inter- or intramolecular forces? Which ones affect the shape a molecule takes on? Why?

This was my answer to the question:

Hydrogen bonds can affect the shape of molecules such as ice. Hydrogen bonds are linear and must therefore form a line. They are major contributors to the shape of a molecule because the hydrogen must make a straight line out of the bond between an electronegative atom, the hydrogen and the other atom that is connected by the hydrogen bond. Hydrogen bonds are very linear bonds.

Is it right?


Bond best answer:

Answer by natureandromeda
Molecules are atoms hooked together. Water molecules are bent because the two pairs of free electons on the oxygen bend the bonds between the oxygen and the hydrogen downward. These are intramolecular forces that affect the shape.

Hydrogen bonds are molecules held together by intermolecular forces. They affect the shape of a bunch of molecules, but not the shape of each molecule itself.

The old making way for the new.

The Paseo bridge is being replaced with the Bond bridge.

The Paseo bridge has been around for about 50 years or so. The Bond bridge is scheduled for a 2011 opening.

These bridges carry north and southbound federal highways I-29 and I-35 across the Missouri river at Kansas City, Missouri.
