Draw a mechanism (with arrow pushing) for the base-catalysed aldol addition and condensation of ethanal with itself, including both steps . Highlight the α hydrogen atoms in your scheme
. A mechanism for hanism for an acid catalysed reaction is as follows. Step 1 Step 2 SH products The rate determining step of the mechanism is step 2. a. Write a rate law for the reaction based on reaction 2 and using the equilibrium based on step1 construct a rate law containing the concentrations [H 1 and [S]. b. Sketch the pH - rate profile of the system (ie what would the plot of rate vs pH look like?)...
Write a mechanism for the acid–catalysed condensation of acetone. Looking at the structure of this product, and of ethylenediamine, suggest how the macrocyclic ligand might form. Can you provide answer for this question, the macro ligand was prepared from ethylenediamine, 50% tetrafluoroboric acid.
A cyanohydrins formation reaction of a ketone/aldchydc is often thought to be mechanistically analogous to base-catalysed hydration reaction. It is usually done in two steps. In the first step the ketone/aldehyde is mixed with a solution of sodium or potassium cyanide, which is followed by the addition of an acid, typically sulphuric acid. Please provide a mechanism for the following two-step procedure. (6') Can a cyanohydrin formation reaction occur at a reasonable rate under an acid-catalysed condition as shown below?...
Given that iridium has a FCC crystal structure, a density of 22.4 g per cubic centimeter, and an atomic weight of 192.2 g/mol, what is the volume of its unit cell in cubic centimeters? For above problem calculate lattice parameter (a) for iridium in cm
Iridium-192 is one radioisotope used in brachytherapy, in which a radioactive source is placed inside a patient's body to treat cancer. Brachytherapy allows the use of a higher than normal dose to be placed near the tumor while lowering the risk of damage to healthy tissue. Iridium-192 is often used in the head or breast. Use the radioactive decay curve of iridium-192 to answer the three questions. us Dobi lio in 100 Ir the initial sample is 6.75 . what...
