Answer:
The answer to your question is A, C, and F
Step-by-step explanation:
Polar covalent bonds are formed between two nonmetals which difference of electronegativity is between 0.5 and 1.7. Use this rule to determine which bonds are polar covalent bonds.
A) H and O 3.44 - 2.2 = 1.24 Polar covalent bond
B) C and H 2.55 - 2.2 = 0.35
C) C and O 3.44 - 2.55 = 0.87 Polar covalent bond
D) C and C 2.55 - 2.55 = 0
E) N and C 3.04 - 2.55 = 0.49
F) N and H 3.04 - 2.2 = 0.84 Polar covalent bond
