In words, give step-by-step directions for drawing the mechanism for the reaction of 1,3-butadiene with HBr.Give explicit information about where "electron-pushing" arrows should begin and end, what new bonds are formed or broken, what atoms have non-zero formal charges, etc. Describe all three steps of the reaction: (a) protonation of carbon 1 (b) the formation of an allylic, resonance-stabilized carbocation intermediate - explain what this is and which carbons have partial positive charge, and (c) attack of Br- to give the 1,2 and 1,4 product.
Quantum number representations - What are the possible values of the four quantum numbers for one electron in a 5d orbital?
If 8 moles of the gas A is placed in a 60L tank with 1 mole of B at 0 degrees celcius and 1 atm, how many moles of gas are present in the tank when the reaction is complete? 2A(g) + B(g) = 3C(g) + D(g)
How much energy is required to heat 10.0 g of ice from -50 to 50 degrees C. The heat of fusion of water is 6.01 kJ/mol and the molar heat capacity is 36.6 J/K mol for ice and 75.3 J/K mol for liquid water.
The activation energy for a particular reaction is 95 kJ/mol. By what factor will the rate constant increase when the temperature is increased from 50 oC to 62 oC?
explain why the chemical formulas AlCl3, PCl3 and CoCl3 are so similar, yet their names are so different.
How many grams of NaCl would be formed from 100 grams of Na2CO3 in the following reaction? Na2CO3 + 2 HCl ? 2 NaCl + CO2 + H2O
To perform a FSO2 analysis using the AO method, you discover that you are out of 3% H2O2. There are 30 samples to test. Will 40 ml of 30% H2O2 be enough to get through all the FSO2 samples and why
Consider all the valence electron pairs of the central atom-both those that are shared in covalent bonds, called bonding pairs, and those that are unshared, called non-bonding pairs or unshared pairs.
