what does it mesn if it has a higher electron density
it can attract cl2 more easily
pi bond
sidewwys overlap of p orbitals
sigma bond
hesd on overlwp of p orbitals
similarities with kekule and delocalised model
both involve the overlappimf of p orbitwls
differences
1) kekule consiste of slternwtimg pi bomds whereas the deloclaised model has the pi bonds delocalised wcross the whole ring
predictions from the delosalised model
1) it does not discoloursie bromine water
2) the dehyrogenwtioj of cyclohexene is -120kjmol so we would expect the dehdrogenetwtiom of benzene ro be -360 but ir is actyally less exothermic thsn oredicted
what do we compwrnth melting poimts of our compounde to in order to idemtify them
a known database
aldedhyde- nitrile
H+ /KCN
what is the normal comonds used in spectroetry
si(ch3)4
when talking about major products what do you say
major product formed from more stable cwrbocwtion
what happnes if yiu add h+ to nh2
