Question 38

Non polar bond

Answer 38

Covalent bond

If electrons are shared equally then the molecule that is formed is neutral

Question 39

Polar bonds

Answer 39

Covalent bond 
Have poles ( one side of the molecule is different than the other, when one atom pulls harder on the electrons the the electron spends more time near that atom so that end is slightly negative
