why do elements make hybrid orbitals
because they form bigger overlap than regular orbitals
what process can predict hybridization of orbitals
VsPR
What is sigma bond
any bond that is isn’t double bonded
pi bond
bond only between two p orbitals
can form
what is constructive interference
when two orbitals are in phase
destructive interference
two orbitals are out of phase and there is a node
symbol for anti bonding orbitals
star
why does antibonding exist
orbitals are constantly changing phase
what is bond order of stable molecule
greater than 1
formula for bond order
sum bonding orbitals - sum anti bonding orbits / 2
paramagnetic
unpaired electrons (magnetic)
diamagnetic
fully paired, non magnetic
what happens to unpaired electrons when near magnet
they orient
does a double bond count as more than one electron group
double and triple bonds are 1 electron group
what does electron group determine
shape of particle
which bonds are stronger pi or sigma
sigma
isomer
same chem formula with different structures and have different properties
molecular orbital
function that represents the state of electron in orbital
bonding orbital
orbital power in energy than atomic orbitals it was formed from
molecular orbital diagram
diagram that determines binding energy and whether or not something is paramagnetic or diamagnetic
What does electronegativity magnitude mean in regard to bonding
when orbital is more electronegative it means the total energy is lower
Which contibutes more to bonding something more electronegative or something less
more electronegative wants electron more
what row can expand its octets
row 3 and beyond
are loan pairs included in hybridization
yes
