16
Q

Ka equation

A

Ka = [H3O+][A-] / [HA]

Ka measures strength of acid

  • high Ka = strong acid
  • small Ka = weak acid
17
Q

pKa equation

A

pKa = -log Ka

Strong acid = low pKa
week acid = high pKa

pKa 10 vs 16 (6 orders of magnitude difference= 1 million)

18
Q

Electronegativity

A

How willing the atom is to except a new electron

19
Q

Ethane

A

H3-C-C-H3

20
Q

Ethylene

A

H2-C=C-H2

21
Q

Acetylene

A

H-C_=C-H

22
Q

Benzene

A

C6H6 circle

23
Q

Saturated hydrocarbons

Alkanes

A

Hydrocarbons that lack pie bonds

Names usually end with -ane

24
Q

Alkyl groups

A

Substituents or branches from parent

25
Q

Calorimeter

A

Experimental device used to measure heat of combustion

26
Q

Energy

A

Branched alkanes are lower in energy (more stable) than straight chain alkanes

27
Q
