what is schrodiner equ for
maths equation for behaviour of protons, electrons and neutrons.
1 of 20
what is octect rule? who invented this.
Lewis. wanting to have 8 valance electrons
2 of 20
two theorys describing molecules
molecular orbital and valance bond
3 of 20
main rule in mo theory
number of atomic orbitals must equal number of new molecular orbitals.
4 of 20
in s orbtials, what does two plus phase ao combination lead to
sigma bonding molecular orbital
5 of 20
in s orbitals, what does the combination of two diff phase atomic orbitals cause
sigma anti bonding molecular orbitals.
6 of 20
cominiation of two p orbtials end on ?
a sigma bonding molecular orbital and a sigma anti bonding molecular orbital
7 of 20
combination of two p orbtials side om
pi bonding molecular orbital and pi anti bonding molecular orbital
8 of 20
in whih molecular orbtial (bonding vs anit bonding) do e- naturally sit in. why.
bonding. its lower in energy and more stable.
9 of 20
shape and ba of sp hybridised orbitals
linear and 180
10 of 20
shape and ba of sp2 hybrdised orbitals
trigional planar and 120
11 of 20
shape and ba of sp3 hybridsed orbitals
tetrahedral and 109.5
12 of 20
what do degenerate orbitals mean
all same energy.
13 of 20
what happens bond stength of hydrogen halidie as you descend halidies. why?
halogens get bigger, sp3 in further away shells from nucleus, less overlap of s and sp3 bond, bond length increases
14 of 20
weakest To strongest intermolecular forces
v der waals, dipole dipole, h bonding, electrostaic/ion ion
15 of 20
describe the two conformational postions
eclipsied- substients closer together, less stable. staggered- more stable as subsituents further away.
16 of 20
what is torsional strain
repulsions when e- in nearing orbitals are too close
17 of 20
three strains in cycloalkanes
torsioanl, angle, steric
18 of 20
describe steric and angle strain
steric-other atoms/groups too close. angle-deviation from tetrahedral 109.5
19 of 20
two optimium shapes from cyclohexane
chair and boat. boat slightly more strain.
