A+
Quiz: From its atomic number of 15, it is possible to predict that the
phosphorus atom has
Ans: 15 protons and 15 electrons
Quiz: Which answer correctly ranks the atoms in terms of decreasing
electronegativity (the highest electronegativity first?)
Ans: O, N, C, H
Quiz: Which atom in the pictured molecule will have the strongest
partial positive charge?
Ans: The C that's in C=O
Quiz: Dr. Haxton says the O-O bond is polar and the C-C bond is
nonpolar. A good student would say ...
a. Yes. O attracts electrons more strongly than C
b. Wrong again, Ralph. Both bonds are nonpolar
c. Right! O is electronegative, so O2 is polar
d. No way. C is more electronegative than O

,e. No, both bonds are highly polar
Ans: Wrong again, Ralph. Both bonds are nonpolar
Quiz: Use your knowledge of electronegativity to pick out the most
polar bond in the list below.
a. C-H
b. O-N
c. O-H
d. N-H
e. O-C
Ans: O-H
O and H are at opposite ends of the electronegativity scale, so the polarity is
very large
Quiz: If you want a molecule that is highly polar, look for one that
contains:
a. C-H
b. O-N
c. H-N
d. S-H

, e. C-S
Ans: H-N
N and H differ in electronegativity more than any other bonded pair of atoms
in the list, making the N-H bond most polar
Quiz: amino
Ans: NH2
Quiz: phosphate group
Ans: one that contains phosphorus
Quiz: hydroxyl group
Ans: OH-
Quiz: carboxyl group
Ans: COOH
Quiz: alchohol
Ans: R-OH
is polar and makes compounds more soluble in water
Quiz: which of the functional groups behaves as a base?
