Question 1

Empirical formula

Answer 1

Ratio of atoms

Ex. C6H12O6 -> CH2O

Question 2

Answer 2

Shows the connectivity between atoms

Question 3

Line angle formula

Answer 3

Carbon: not shown

Hydrogen on C: not shown

Question 4

Acid base:

Arrhenius

Answer 4

Acid: H+ doner
Base: (-)OH donor

Question 5

Acid base:

Bronsted-Lowry

Answer 5

Acid: H+ donor
Base: H+ acceptor

Question 6

Acid base:

Lewis

Answer 6

Electron pair acceptor

Electron pair donor

Question 7

How to obtain ka

Answer 7

Ka= [H+] [A-]
———–
[HA]

Question 8

Which acid is more stable; one that is more electronegative or one that isn’t?

Answer 8

Electronegative bcs wants to hold onto the e- closer and so stable

Question 9

Which acid is more stable (during rxn): one that is a larger atom or one that isn’t?

Answer 9

The larger atom is more stable bcs pain is spread out

Question 10

Which compound is more stable: one that has a resonance or one that doesn’t?

Answer 10

The one that has the most resonance is more stable bcs resonance; means spread out damage

Question 11

Molecular orbitals

Answer 11

#MO         =  #AO (antibonding orbitals)
Creates bond  |  Breaks bond

Question 12

Formal charge

Answer 12

(# VE) - (#VE in bonded atom)

Remember: one line bond is just 1 electron

Question 13

Hybridization

Answer 13

When atomic orbitals combine to form hybrid orbitals

S orbitals: + with a s
P orbitals: plane with xyz

Question 14

How to determine hybridization

Answer 14

Count the regions of high electron density

C: or -C or =C still one region

4. ..sp3
5. ..sp2
6. ..sp

Question 15

Isomers

Answer 15

Different molecules with same molecular formula

Question 16

Stereoisomers

Answer 16

Same connectivity, different orientation in space

Ex.
Angle formula M and W same amount of connectivity

Question 17

Cis

Answer 17

Same side _/

Question 18

Trans

Answer 18

Opposite side _
