Fall 06
Quiz #1
Ch 1-3
(20 questions for 20 points)
Name If you do not want your graded quiz placed in the box outside my office, then please check here (1-10) Are True or False. 1)
An orbital can hold up to two electrons
2)
Electrons have a much lower mass than protons and neutrons
3)
All π bonds are considered to be polar
4)
Carbon is more electronegative than Nitrogen
5)
Butane has more ring strain than cyclopentane
6)
The electron configuration of Beryllium is 1s1 2s 22p1
7)
Carbon has 8 electrons but only 6 valence electrons
8)
sp2 hybrid orbitals give rise to bond angles of 109.5°
9)
An sp2 hybridized atom has an unhybridized p orbital, which lies at right angles to the plane of the hybrid orbitals
10)
A σ bond places electron density directly between the atoms being bound together and is therefore stronger than a π bond
11-13) Draw Lewis structures (lines for bonds, dots for lone pairs of electrons) for: 11) cyclopentane
12)
CH3CH2N(CH3)2

O F3 C
14) How many Carbons are in this molecule? 15) How many Hydrogens? 16) How many π bonds? 17) How many sp2 hybridized atoms? 18) What is the C-N-C bond angle predicted to be? 19-20) For butane CH3(CH2)2CH3, using any format you wish (Sawhorse / sticks and wedges / Newman projection) draw: 19) the anti conformation
20) the totally eclipsed conformation
*BONUS QUESTION for 1 extra point* What is the common trademarked brand name of the drug in Q14 ?
