Polarity

Question 1

define electronegativity

Answer 1

the ability of an atom to attract the shared electron towards itself in a covalent bond

Question 2

why are diatomic molecules non polar

Answer 2

there are no dipoles in the bonds since both atoms have the same electronegativity so both have the same ability

Question 3

if a molecule contain polar bonds and the bonds are on the same side of the central atom, is he molecule polar or nonpolar

Answer 3

polar

Question 4

if a molecule contains polar bonds and the bonds are spread around the central atom, is the molecule polar or non polar and why

Answer 4

non polar
- the dipoles cancel out

Question 5

which shaped molecules tend to be non polar due to dipoles cancelling out

Answer 5

linear
trigonal pyramidal
tetrahedral

Question 6

if a molecule has different bonds around the central atom, and some of them are polar whilst others are not, is it polar or non polar and why

Answer 6

polar
- some bonds have stronger dipoles than others
