The benzene ring modify the reactivity of neighboring group in the benzylic position much like a double bond alters the reactivity of groups in the allylic position. benzylic cations, anions, as well as radicals are more stable than simple alkyl intermediates.
a) Utilize resonance structures to show the delocalization over four carbons of the positive charge, unpaired electrons and negative charge of benzeyl cations, radical, anion.
b) Tolunene reacts with bromine in the presence of light to give benzyl bromide. Intend mechanism for the reaction.
A three-step industrial process involves both heat and work. Calculate the overall change in energy DE for the entire process, given these three individual steps.

How much entropy does this produce per hour in the surroundings at 25.4 °C? Assume the heat transfer is reversible.
Determine which H atom transition (ninitial,nfinal) was responsible for the emission of a photon with a frequency of 6.91 x 1014 Hz.
Alkynes can be hydrated in the presence of acid and HgSO4, by electrophilic addition of a molecule of water to the triple bond. The reaction proceeds by way of a carbocation intermediate
Calculate the maximum mass of calcium metal that should be used in this experiment with a 50mL eudiometer tube for gas collection. Assume that the hydrogen generated occupies 45 mL at STP. The experiment is: reaction of .054 g of Al with 100 mL of..
lemon juice has a ph of about 2.5. Assuming that the acidity of lemon juice is due solely to citric acid, that citric acid is a monoprotic acid,
where all compounds are assumed as covalent then determine which reaction must be endothermic and also explain your answer briefly?
the constant pressure molar heat capacity of a compound is found to vary with temperature.cpm 18.15 0.430t
The confirmation test for Ag^+ is to add HNO3 to the [Ag(NH3)2] ^+ and see if a precipitate of AgCl forms. Where does the Cl ^ - come from. Why does adding HNO3 make AgCl precipitate
calculate the heat of reaction for 2PbS +3O2 yields 2PbO +2SO2 given the following information. PbS= -93.3 kj/mol. PbO=-219.7. SO2=-296.6. O2 = 0. I got -846kj, is that correct
