Electronegativity Flashcards
(8 cards)
1
Q
Definition
A
Relative tendency for an atom in a covalent bond to attract an electrons to itsefl
2
Q
Polarity
A
Difference in electronegativites
3
Q
Dole
A
Difference in charge between the two atoms caused by shift in electron density
4
Q
Permanent dipole
A
Polar molecules form dipoles, Weak electrostatic forces of attraction between charges
5
Q
Intermolecular forces
A
Induced dipole, vanderwaals
Permanent
Hydrogen
6
Q
More vanderwaals
A
Means more electrons increase greater MR mean more vanderwaals and is stronger
7
Q
Hydrogen bonding
A
Only between FON
8
Q
Ice
A
When ice cools it forms lattice, ice is less dense than water as the h20 molecules are futher apart
