THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP'
s earlier story is below.
HUNTSVILLE, Ala. (AP) - A woman opened fire during a biology faculty meeting
at the University of Alabama's Huntsville campus Friday, killing three
people and injuring at least one more.
The shooter was in custody, but university spokesman Ray Garner said he
could not identify her or the victims. Local television

Q1. Predict the trend in gas-phase acidities for the followin compounds: H2C
=CI (iodoethene), H2C=CBr (bromoethene), H2C=CCl(Chloroethene). Which hydrogen
should be most acidic in each case? why?
Q2: Use an orbital mixing diagram to show how Hg2+ and S2- (负二价) have a
stronger acid-base interaction than Hg2+ and O2- （负二价）
不是学化学专业的，不太会做这样的题，请高手赐教，谢谢

bromoethene
BR shows higher electronegtivity than I , thus stable the corresponding
carbonanion.
d orbital dorbital interaction HG S
better than d s orbital interaction between hg o

H2C
hydrogen

Thank you for your answer. You mean Bromoethene is more stable then the
other two, which means the hydrogen is more stable than the ones in the
other compounds, so it is less acidic?
So the hydrogen in iodoethene should be the most acidic?
Thank you so much.

The silver lining (although it is around a really dark cloud) is that there
will be at least 4 faulty postions open in that doomed university.
And I think that the tenure approval rate would be higher in the following
decade in that university.
May all the dead rest in pease.
May all the new faulty members, especially assistant professors, live
happily thereafter.

tenure制度很好，但钱太少了变成狗屎。
10年前, NIH RO1通过率是25%，tenure保证有位置的人有起码的能力。
现在通过率是8%，tenure就变成了非常可怕的压力。

According to a faculty member, the professor had applied for tenure, been
turned down, and appealed the decision. She learned on Friday that she had
been denied once again.
