b. Rank the following the following correlation coefficients
from the strongest to the weakest: ___________ y=14.5+6.3x r = 0.65
___________ y= 72.9-7.6x r = -0.87 ___________ y=23.0+12.6x r =
0.79 ___________ y=23.9-5.98x r= -0.88 ___________ y=78.0+9.0x r=
0.86
12a. Alaska Career College is in the process of selecting a new
Academic Dean. Before making a final selection it wants to know how
its staff feels about the final prospective candidate. Nielson Corp

1) Rank the following from the strongest acid to the weakest
acid. Explain with reasons please.
A) CH3CH2OH
B) CH3OCH3
C) CH3—NH—CH3
D) CH3—C≡CH
E) CH3—CH=CH2
2) Draw all possible isomers that have the molecular formula
C5H12O and name them using the systematic IUPAC name.
3) The following compound has 2 isomers. One isomer has a dipole
moment of 0 D, whereas the other has a dipole moment of 2.95 D.
Propose structures for the 2 isomers that are consistent...
Rank each substance above from strongest to weakest
intermolecular force. Do not look up these substances' physical
properties...determine the ranking based on general intermolecular
force principles. If you predict an "anomaly" (i.e. a "LDF only"
molecule with greater intermolecular forces than a dipole-dipole or
hydrogen bonding molecule), you must briefly state your reasoning.
Please justify why you put each molecule in its order.

Mutliple step synthesis for 4-bromoacetanilide from aniline
1. during the synthesis of aniline from nitrobenxe, explain why
it was necessary to make the solution alkaline (addition of
NaOH)
2. During filtration, why is it important to only wash the solid
with ice-cold solvent?
3. Why is it necessary ti acylate aniline prior to
bromination?
4. If the synthesis of p-bromoacetanilide also provided a small
amount of o-bromoacetanilide after the crystallixation step, how
would that influence the melting point range od...
