U1 - Intramolecular Forces of Attraction Flashcards
1
Q
•Intramolecular Force of Attraction
A
- Attractive forces within a bond between atoms
* Ionic, Polar, Non-Polar
2
Q
•Pure Covalent/Non-Polar Covalent Bond
A
- non-metal + non-metal
* almost equal sharing of e-
3
Q
•Polar Covalent Bond
A
- non-metal + non-metal
* unequal sharing of e-
4
Q
•Partial Negative d-
A
- Assigned to the atom with the higher EN value in a bond
* e- are more attracted
5
Q
•Partial Positive d+
A
- Assigned to the atom with the lower EN value in a bond
* e- are less attracted
6
Q
- Dipole or Dipole moment
* -|—->
A
- Direction in which dipoles are being pulled
- From partial positive to partial negative
- d+ -|—–> d-
7
Q

A
- Surrounds a lone pair of e-
* Has a small dipole
8
Q
•Range of Difference in EN
A
•0-0.4; non-polar covalent
•0.4-1.7; polar covalent
•1.7-3.3; ionic
guideline, not a rule
