which is more stable cis or trans isomers 

Lösung anzeigen
TESTE DEIN WISSEN

trans-isomers cause it has less steric strain than cis isomers

TESTE DEIN WISSEN

how do you Calculate formal charge and steric number 

Lösung anzeigen
TESTE DEIN WISSEN

-FC: valence e-(bonds+dots)

-steric number (sum of atoms and nonbonding electron pairs around central atom). Ex.

1. Catalysts increases _______, lowers ______ 

2. are catalysts consumed in reaction 

Lösung anzeigen
TESTE DEIN WISSEN

1. reaction rate, activation energy

2. catalysts are not consumed in the reaction, they are the same at the end of reaction as it was at start

TESTE DEIN WISSEN

How is degree of unsaturation affected with O, Halogen (Br, F, I ), N

Lösung anzeigen
TESTE DEIN WISSEN

-Oxygen has no change to the number of hydrogens 

-Halogens: subtract number of halogens to the number of hydrogens (ex. C3H4BrF if the same as C3H2: I subtracted two more hydrogens b/c there were two halogens) 

-Nitrogen: add the number of nitrogens from number of hydrogens (ex. C5H5N is the same as C5H6: I added hydrogen b/c there was nitrogen)

TESTE DEIN WISSEN

carbon with a pos. charge

TESTE DEIN WISSEN

1. Out of a group of alkenes or several alkenes, which would be more stable 

2. which alkene would be more stable, an alkene with two small alkyl groups attached to the double vs. one large alkyl group 

Lösung anzeigen
TESTE DEIN WISSEN

1. the alkene with the greatest number of alkyl substituents on the double bond is usually the most stable one 

2. an alkene with two small alkyl groups attached to the double bond would be more stable

TESTE DEIN WISSEN

sp3, sp2, sp: rank by length, strength, and acidity 

Lösung anzeigen
TESTE DEIN WISSEN

sp3- long, weak, not that acidic 

sp2- medium length, medium strength, medium acidity 

sp- short, strong, acidic 

Reason: the greater the 's' character the electrons are held closer to the nucleus so they are stronger, shorter, and acidic

single, triple: rank by length and strength 

Lösung anzeigen
TESTE DEIN WISSEN

-single is longer but weaker 

-triple is shorter but stronger

TESTE DEIN WISSEN

1. why is Sulfur more acidic than oxygen even though oxygen is more electroneg. 

Lösung anzeigen
TESTE DEIN WISSEN

1. B/c sulfur is bigger (or bigger atomic radii), As the atom size increases down a column on the periodic table, the acidity increases.

How do you determine which subsituent has highest priority 

Lösung anzeigen
TESTE DEIN WISSEN

1a. Assign higher priority to the group containing the atom of higher atomic number that Is attached to the carbon, (ex.
−CH2CH2I
is a higher priority than −CH2CH3 b/c (the first C atom is the same for both, There is two C-H bonds so never mind that); look at the second carbon, in the first one there is two C-H bonds and one C-I bond, Iodine has a higher atomic number so it would be first.  

1b. Assign priority to the group that has higher atomic mass attached to the carbon
