Determine if the compound is ionic or covalent. The ionic compounds are typically composed of metals and nonmetals. The metals, with the exception of hydrogen, are located to the left of the periodic table, and the nonmetals are located on the right side. An example of an ionic compound i...
1 The reactive metabolite responsible for paracetamol-induced hepatotoxicity, postulated to beN-acetyl-p-benzoquinoneimine reacts with N-acetyl cysteine. 2 An adduct is formed by an SN2 mechanism and paracetamol is produced by a redox reaction. ...
How do you distinguish R and S configuration from a chiral center? Chiral centre: Chiral centre or chiral carbon can be defined as that carbon centre which is connected to four different moieties or groups so that the molecule's mirror image is non-superimposable on itself. The property of...
This situation doesn’t come up very often in introductory organic chemistry courses, but when it does, it’s usually when you’re sitting in an exam hall. What makes theretro-Diels Alder reaction exam-question catnip for instructors is that it asks you to apply concepts you already know,bu...
Explain how a buffer is able to resist changes in pH. What are buffers? Provide an example of where buffers are used in the body and why? Why do the bodies cells become more acidic as a result of cellular respiration? Explain the action of a buffer using the common ion effect. Expla...
We’re just saying that thepatternof an acid-base reaction is followed (i.e. form and break a bond at the same H). 3. The Principle of Acid-Base Mediocrity In what direction do you think acid-base reactions are favored? Do they spontaneously go from stronger acids to weaker acids, or...
The diagram represents a reaction. Use the diagram to answer the question below. (Image) a. Is the reaction exergonic or endergonic? b. Is Delta G reaction positive or negative? Examine the following SN2 reaction. Draw an energy diagram. Draw an energy diagram. Label th...
How could you prepare the following ketone below by reaction of an acid chloride with a lithium diorganocopper reagent? Gilman Reagent: A Gilman reagent is also known as {eq}R_2CuLi. {/eq} Here, R can be an aryl group as well as an alkyl ...
In particular, CETP transfers CEs from HDL to LDL and VLDL (very low density lipoprotein) with the complementary transfer of TGs from LDL and VLDL to HDL6. It is seen that the hetero exchange of neutral lipids by CETP between atheroprotective HDL and atherogenic LDL or VLDL has an outcome ...
滤镜的滥用，导致了艺术创作的[u] [/u]。在一些热播剧集的带动下，电视剧制作逐渐形成了相对固定的调色法则，古装剧追求“高级”的低饱和度、悬疑剧的色调越来越暗沉、甜宠剧的柔光愈加刺眼···滤镜风格成为最显眼的[u] [/u]标志，题材、人物、情绪、冲突等方面的内在差异却被忽略了。 依次填入画横线部分...
