line notation
-towards
-away
electrons sit in an atomic orbital what are the 4?
each orbital hold-- number of electrons?
sp--has two electron domains shape and angle
sp2 has 3 domains --shape and angle
sp3 has 4 domains --shape and angle
direct orbital overlap= freely rotation what kind of bond
pi bond have -- rotation
double bonds will always have 1 -- and 1--
triple bonds will always have 1-- and 2 --.
-s,p,d,f
-2
-linear, 180
-trigonal planar, 120
tetrahedral ,109.5
sigma
restricted
pie, sigma
sigma, pie
pie bonds can be
carbon with a formal positive charge
carbocation form which sp?
more electronegative elements are better for --charges
more electropositive element are better for --charges
resonance with more -- atoms are more stronger
-delocalized
-carbocation
-sp2
-negative
-positive
-neutral
Bronsted Lowery focus on proton
Acid
base
proton
acid tried to get its conjugate base
base tries to get its conjugate acid
the side with the weaker acid will be-- also higher the pka
transfer
donates a proton
accepts a proton
postive charge H ion
favored
Lewis Model focus on
acid
base
you will not get --- bases like brownstead lowry
if every single acid looses a proton
if very loose very few proton then
what will represent acidity?
larger Ka= smaller pka
what will represent basicity?
lower pkb=
-electrons
accepts a pair of electron
donates a pair of electrons
-conjugated acid or base
-strong base
-weak acid
-pka
=strong acid
-pkb
-strong base
if pka is greater then ph =
ph is greater then pka =
bases depropanate or propanate?
acids depropanate or propanate?
hydrogen floride
CH3 methane
s orbitals shape? more elctronegative
p orbital shape? less electronegative
sp then sp2 then sp3 more acidic or basic
what is the most elctronegative element
propante// acid
deporpanate// base
depropanate
propanate
strong acid/ weak base// its alwayas opposite
strong base//weak acid//
-spherical
-lobes
-acidic
-flourine
NH/OH/FH is used what kind of bond?
Dipole dipole happens what kind of 2 atoms
dispersion reaction happen between what 2 atoms?
solid -> liquid
liquid-> gas
-hydrogen bond
-between partial charges
-between nonpolar molecules
-melting
-boiling
