BIO 3100 Test Banks BIO 3100 Lecture Exam I-A February 14, 2008 1. Universal features of all living cells include all of the following except: (a) nucleus or nucleoid (b) plasma membrane (c) cytoplasm (d) centrosome 2. An open system is one (a) that exchanges neither matter nor energy with its surroundings plasma membrane (b) that exchanges energy but not matter with its surroundings. (c) that exchanges both matter and energy with its surroundings. (d) that exchanges matter but n...

In the Sⁿ1 reaction (2-chlorobutane, 2-chloro-1-butene, or 3-chloro-1- butene) is the most reactive R-X. - 3-chloro-1-butene The energy required for an electronic transition across HOMO-LOMO gap is (directly, additionally, or inversely) proportional to the wavelength of light absorbed for that transition and shifted to (shorter, longer, or the same) wavelength for more conjugated molecules. - inversely, longer UV light excites an (n to pi*, sigma to sigma*, sigma* to sigma, pi* to pi, or...

Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? - answer1. An atom must have a P orbital or a lone pair of electrons. 2. ...

Org II (Hamann) Chapter 17 HW – Pi Systems Name 1 Draw the structures of the following compounds a) cyclopentadiene (explain why the numbers for the double bonds (1,3-), which are formally require d, are usually omitted. I.e., why is only one isomer possible; why not 1,2- or 1,4-cyclopentadiene? 1,2-cyclopentadiene would contain an allene, a linear C=C=C unit that would make the ring too strained. 1,4- cyclopentadiene would actually be the same molecule, but numbered incorrectly. Hence the use...
