OChem 2 Explanations
Why is Cl2 non-selective?
Why is Br2 selective?
Design an exp to determine if a rxn occurs via radicals not ionic (SN1, SN2, etc).
What is the order of importance in which structures contribute to the hybrid
What is resonance?
e- delocalization through conjugated systems (need p orbitals)
Why is the length of the C-C for conjugated dienes unusually short? (2 arguments)
Completely conjugated →___ λmax ∴ absorbs ___ wavelength (UV light)
high; greater
Why is the kinetic product faster than the thermodynamic product?
For Diels Alder rxns, why does the diene have to be in s-cis conformation?
Draw MOs & Frost Circle for the benzene.
Draw MOs for 1,3 - butadiene.
Draw Frost Circle
Why is breaking Ar the RDS?
ELECTRONIC ARGUMENT
Why is methyl an o/p director?
Why is NO2 a meta director?
