Intramolecular Vs Intremolecular Forces Flashcards
What is Intramolecular?
Intra = within something
Intramolecular forces are strong bonds that hold 1 molecule together. The bond is inside a molecule.
Describe the visual of intramolecular using hydrogen and oxygen as examples
the Intramolecular bonds hold the H atoms to the O atom in a covalent bond.
See visual in Photos
What is intermolecular?
Inter = outside of something
Intermolecular forces are weak bonds because of polarity and how neighboring molecules are attracted to each other.
Describe the visual of intremolecular using hydrogen bonding as an example
Intermolecular bonds are outside a molecule.
For example: Hydrogen bonding
See visual in Photos
Can intermolecular bonds be breaken easily since they’re weak?
True or False
False. It takes a lot of energy to break these forces. As a result, boiling and melting point increases.
What is an example of this increase in boiling and melting points in terms of intermolecular bonding?
It takes 100C of energy to break the hydrogen bonds and turn liquid water to water vapor.
Name 2 biomolecules hydrogen bonds are responsible for?
The shape of DNA and proteins
How does the DNA ladder form?
Hydrogen bonds between nucleotides (A, T, C, G) to hold the 2 sides of the DNA ladder together.
How does the double helix structure of DNA form?
Hydrogen bonds form between the side chains in the sugar-phosphate backbones to create the coiled, double helix structure.
How does hydrogen bonds contribute to protein folding?
Hydrogen bonds between amino acids contribute to the unique folding and 3D shape of proteins.
Name and describe the 2 structures hydrogen bonds contribute to in protein folding.
- Hydrigen bonds contribute to the secondary structure of proteins by creating α-coils and β-sheets.
- Hydrogen bonds also contribute to the tertiary structure by pulling different parts of the protein chain closer together to create the proteins 3D structure.
Name the 4 key elements that bond with hydrogen and can make hydrogen bonds
Hydrogen bonds form when fluorine, oxygen or nitrogen bond with hydrogen.
