What type of bonds make up a single bond
Sigma bond
What type of bonds make up a double bonds
One sigma, one pi
What type of bonds make up triple bonds
One sigma, two pi
sp3 hybridization follow which bond angle
109.5
sp2 hybridization follows which bond angle
120
sp hybridization follows which bond angle
180
A carbon atom that has four different groups bonded to it is referred to as a
Chiral carbon
When designating molecules as R or S, what do these two indicate
R = clockwise, S = counterclockwise
Under which cercumstance do you change a molecule from R to S
When the group with the lowes priority (4) is on the horizontal axis
Which type of compounds possess a plane of symmetry
Meso Compounds
Pairs that have chiral centers and nonsuperimposable mirror images
Enantiomers
Pairs that have chiral centers and but different arrangement of atoms
Diastereomers
The type of designation used for simple alkenes in which one non-hydrogen group is attached to each side of the double bond
Cis-Trans designation
The type of designation used for more complex alkenes (priority is used and you're looking for where 1 and 2 are located about a double bond)
(E)-(Z) designation
If DAT asks to rank compounds according to solubility, what do you look for
Electronegativity (more electronegative means, more soluble in water)
Nucleophiles "love" positive or negative charges
Positive charges
Electrophiles "love" positive or negative charges
Negative charges

SN1
How many steps does it take to complete an SN1 reaction
2
Between SN1 and SN2, which of the two reactions favors a strong nucleohile
SN2 (necessary to push out weak leaving group)
SN1 or SN2 rxns have rate laws that show direct dependence of the rxn rate on the concentrations of both alkyl halide and nucleophile
