Hydrogen Bonds Flashcards
(7 cards)
1
Q
Are hydrogen bonds weaker or stronger than ionic and covalent bonds?
A
Weaker
2
Q
How can hydrogen bonds become stronger?
A
Large numbers of them can exert a strong force
3
Q
What are hydrogen bonds a result of?
A
Unequal charge distribution on a molecule (making them polar)
4
Q
What can hydrogen bonds form between?
A
Hydrogen atoms that are already covalently bonded to an oxygen, nitrogen or fluorine atom
5
Q
What do hydrogen bonds do to the viscosity of water?
A
Increases it
6
Q
What is viscosity?
A
The ability to resist motion
(Meaning water can hold its shape until too much tension is added)
7
Q
What are hydrogen bonds?
A
A type of weak bond formed between an electropositive hydrogen and an electronegative atom like oxygen
