Polarity And Intermoleulcar Forces Flashcards
1
Q
Electronegativity
A
An atoms ability to attract the electron pair in a covalent bond
2
Q
How is electronegativity meaasured
A
Pauling scale
N,O,F most electronegative
Increases across periods + decreases down groups
3
Q
How do London forces arise
A
-uneven distribution of electrons
-causes temporary dipole in a molecule
-causes induced dipoles in neighbouring molecules
