Module 5.5 Bond Polarity

Question 1

Bond Polarity fill in arrows

H - C
H - O
O - S
O - C

Answer 1

H - C = non polar (difference no more than 0.4)

H -> O = Polar (difference more than 0.4)

O

Question 2

Attractiveness ( electronegativity) for

H = ?
L = ?
Na = ?
K = ?

Answer 2

H = 2.1
L = 1.0
Na = 1.0
K = 0.8

Question 3

N = ?
P = ?

Answer 3

Be = 1.5
B = 2.0
C = 2.5
N = 3.0
P = 2.1

Question 4

S = ?
F = ? 
Cl = ? 
I = ?

Answer 4

O = 3.5
S = 2.5
F = 4.0
Cl = 3.0
I = 2.5
