In organic chemistry, functional groups are specific organizations of atoms that give a molecule characteristic properties. Some examples of functional groups include alcohols, ethers, amines, and more. Answer and Explanation:1 An ether in organic chemistry is a functional group that has an oxygen at...
The reaction between two equivalents of BiCl3 and (o‐(Ph2P)C6H4)3Bi yielded (o‐(Ph2P)C6H4)BiCl2(THF), the structure of which indicated Bi...P interactions and thus a pronounced Lewis acidity at the bismuth center that was confirmed by the Gutmann‐Beckett method...
In chemistry, water has many uses. Name three of these uses. What is analytical chemistry? What is quenching? Define hydrodynamic voltammetry. What is meant by the term trace element? What is the activity of water at 11 bar and 298 K?
Due to the influence of the chlorine atom, its alkalinity is slightly weaker than that of aniline. This substance can be used as an intermediate in organic synthesis and medicinal chemistry, and it is widely used in the structural modification and production of drug and pesticide molecules in fi...
NBS is a chemical reagent used in organic chemistry in electrophilic addition reactions and radical substitution. In bromination of olefins; in oxidation of alcohols to aldehydes and ketones and of aldehydes to acid bromides. N-Bromosuccinimide (NBS) in combination with LiBr can also be used in ...

Heptanal or heptanaldehyde is an alkyl aldehyde. It is a colourless liquid with a strong fruity odor, which is used as precursor to components in perfumes and lubricants. Emde et al. reported [1] its application on the total syntheses of two acetogenins, squamocin A and squamocin D, ...
Under a nitrogen atmosphere, magnesium powder (0.10 g, 4.5 mmol, 1.5 equivalents) and elemental iodine (8 mg, 0.03 mmol, 0.01 equivalents) are added to a dry reaction flask. Then, 3.0 mmol of Cyclopropyl bromide is dissolved in 6.0 mL of anhydrous tetrahydrofuran (THF) in another dry flask...
My Thought Process: Use NaOH for Sn2 mechanism because this is simple and substrate is primary. Actual Answer: Reagents to use are t-BuOK (implying E2) then BH3 THF then H2O2, NaOH (implying adding H and OH antimarkovnikov)Where did I go wrong? If I am able to choose the reagent, ...
自然人甲与房地产开发公司乙签订一份商品房买卖合同,乙提出,为少交契税,建议将部分购房款算做装修费用,甲未表示反对。后发生纠纷,甲以所付装修费用远远高于装修标准为由,请求法院对装修费用予以变更。该装修费用条款效力应如何认定?( )。
