Question 1
The lines on the above drawing of caffeine indicate:
A.
Covalent bonds
B.
Hydrogen bonds
C.
Ionic bonds
D.
Polar bonds
Feedback
Correct. Covalent bonds are drawn as straight lines.
Question 2
Will O
form a polar covalent bond?
A.
Yes, because oxygen is very electronegative.
B.
Yes, because oxygen is not very electronegative.
C.
No because hydrogen is needed to form polar covalent bonds
D.
No, because both atoms are equally electronegative.
Feedback
Incorrect. Oxygen is electronegative, but polar covalent bonds are formed when
a molecule has atoms of different electronegativity. This molecule has 2 oxygen
atoms; so both have the same electronegativity.
