Chem - Bond/structure - polar and no polar

Question 1

Determine the polarity of nonpolar and polar MOLECULES

Answer 1

Polar bonds = dipoles do not cancel out
Non polar bonds = dipoles cancel out

Question 2

Determine the polarity of non polar and polar BONDS

Answer 2

Non Polar = When there is no electronegativity difference therefore the bond dipoles will cancel out
Polar = When there is a difference in electronegativity this means the bonding electrons are unevenly shared and the bond dipoles do not cancel out

Question 3

Determine the solubility for a non polar bond

Answer 3

When a non polar and polar bond are mixed together the attraction between the polar and non polar molecules are weaker and will not release sufficient energy to separate the two molecules therefore non polar bond dose not dissolve

Question 4

Determine the solubility for a Polar bond

Answer 4

When a polar bond is mixed with water which is polar the energy released when attractions form between the polar bonds is grater then the energy needed to separate the molecules therefore dissolves in water
