Explain simple chemical tests to distinguish between the compounds in each of the subsequent pairs. Explain exactly what you would do and what you would see.
i) Propionic acid as well as methyl propionate
ii) p-Bromobenzoic acid as well as benzoyl bromide
iii) Benzonitrile as well as benzamide
iv) Succinic acid melting point 182oC as well as 2-napthonic acid melting point 183oC
v) Acetic anhydride and n-butyl alcohol
vi) Malonic acid melting point 130oC as well as maleic acid melting point 131oC
What product was formed and why did this route to the ether fail. Suggest a different substitution reaction that should yield the desired product.
Where would we predict benzene to absorb if we treated the pi-electrons as particles on a ring (radius 1.39 A)? What is the % error? I'll give you a hint.
Trimix is used for very deep diving. It is composed of three gases, usually helium, nitrogen and oxygen. The composition is denoted as percentage of oxygen / percentage of helium, e.g. 17/50 is Trimix with 17.0% oxygen, 50.0% helium and the rest i..
Magnesium hydroxide, the active ingredient in milk of magnesia neutralizes stomach acid , primarily HCL, according to the reaction: Mg (OH)2 (aq) + 2 HCL(aq) ---> 2 H2 O (l) + Mg(OH)2(aq).
Amongst the following pairs, predict which one would be the best nucleophile and justify your answer.i) CH3OH vs. CH3O-
If N2 and H2 at preliminary pressures of 1.5atm and 2.5 atm respectively were allowed to react at 300K as well as the total pressure at equilibrium is 4.0 atm, what is the Kp
NH3 is a weak base (Kb=1.8 x 10^-5) and so the salt NH4Cl acts as a weak acid. What is the PH of a solution that is 0.049 M in NH4Cl?
The total pressure for a mixture of N2O4 and NO2 is 1.5 atm. If Kp=7.1 (at 25 degrees C) calculate the partial pressure of each gas in the mixture. 2NO2(g) N2O4(g)
If iron is oxidized to Fe2+ by a copper(II) sulfate solution, and 0.538 grams of iron and 13.0 mL of 0.40M copper(II) sulfate react to form as much product as possible.
Experiments have shown that the average frequency of chirping by a snowy tree cricket depends on temperature as shown below
a container holds 2,0 of gas. the total average change in KE of gas molecules in the container is equal to the the sum of KE of an 8,0x10^-3 -Kg bullet with speed
Two 20.0g ice cubes at -12.0^degree C are placed into 235g of water at 25.0^degree C. Assuming no energy is transferred to or from the surroundings, calculate the final temperature of the water after all the ice melts
