Answer 19

in plane called equatorial (120 deg. apart)

N/ S are axial (180 apart and 90 from each other )

Question 20

Octahedron

Answer 20

4 pairs in plane are 90 from one another and axial are 180 apart and 90 to the plane

Question 21

bonds in polyatomic molecules are

Answer 21

dipole bonds

Question 22

CO2 dipole is cancelled

Answer 22

because it is linear

Question 23

H20 dipole is not cancelled

Answer 23

because molecule is bent

Question 24

trigonal pyramidal

Answer 24

yes dipole

Question 25

trigonal planar

Answer 25

no dipole unless ‘b’ molecule is different

Answer 28

sp3d

Question 29

octahedral

Answer 29

sp3d2
