Bond polarity

Question 1

when does a polar covalent bond occur ?

Answer 1

when the 2 atoms in a covalent bond have a different electronegativity

Question 2

when does a non-polar covalent bond / pure covalent bond occur ?

Answer 2

when the 2 atoms in a covalent bond have the same electronegativity

Question 3

what does a polar covalent bond mean ?

Answer 3

the more electronegative atom has a greater share of the 2 electrons and is delta - while the less electronegative atom has a lower share and is delta +

Question 4

what is an example of a polar covalent bond?

Answer 4

H-Cl

Question 5

what is an example of a non-polar covalent bond ?

Answer 5

Cl-Cl

Question 6

what do bonds that are polar have ?

Answer 6

a bond dipole moment

Question 7

at is a bond dipole moment ?

Answer 7

a bond dipole moment is a measure of the strength and direction of the polarity in the bond, so the bigger the difference in electronegativity, the bigger the bond dipole moment

Question 8

what kind of bonds in organic molecules are not regarded as polar, even though there is a small difference in electronegativity?

Answer 8

C-H
