Electronegativity

Question 1

What is electronegativity?

Answer 1

the degree which atoms force electrons to be closer to them in a bond

Question 2

if a bond is formed between two atoms with varying electronegativity, one with a higher electronegativity than the other, where would the electrons be closer to?

Answer 2

the more electronegative atom

Question 3

Covalent bonds are formed when there is a _____ difference in electronegativity

Answer 3

minor/small

Question 4

Ionic bonds are formed when there is a ____ difference in electronegativity

Answer 4

great/big

Question 5

What is London dispersion force?

Answer 5

a temorary formation of dipoles between two atoms due to random electron movements, which makes the molecule slightly charged

Question 6

Where can london dispersion force be present?

Answer 6

By having a large molecule

Question 7

Dipole Dipole bonds

Answer 7

the combined vector of charge directions generating an overall charge direction

Question 8

Where can dipole dipole force be present?

Answer 8

In asymmetric molecules with polar bonds

Question 9

What is a hydrogen bond force and how does it work?

Answer 9

Hydrogen has low electronegativity, when it forms bonds, the bond is likely to be highly polarized due to the electronegativity difference, and thus creates intermolecular force

Question 10

List these 4 intermolecular forces from weakest to strongest:

Ionic
London dispersion
Dipole Dipole
Hydrogen bond

Answer 10

London dispersion
Dipole Dipole
Hydrogen Bond
Ionic
