What type of acid is phthalic acid? Is it acid anhydride or acid halide? Of the following, which is the strongest acid? (a) HIO (b) HIO_2 (c) HIO_3 (d) HIO_4 Which acid below, based on its K_a value, is the strongest acid? Acid 1: K_a = 4.96 x 10^-11 Acid 2: K_...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
What type of acid is phthalic acid? Is it acid anhydride or acid halide? Identify the acid anhydride of the given ternary acid. H2SO4. How to prepare 1 L of 2.5 M nitric acid from 69 % of concentrated nitric acid? What is the name of an acid with the formula HNO2? a) nitrous ...
M. (2020). Halide-Accelerated Acyl Fluoride Formation Using Sulfuryl Fluoride. Organic Letters, 22(16), 6682–6686. The authors report a novel method for SO2F2-mediated substitution reactions starting from carboxylic acids. They determined that the SO2F2- mediated acid activation forms a ...
Alternatively, the compound can be prepared by heating boric oxide or boric acid with ammonium chloride or an alkali metal cyanide. Purified product can be obtained by high temperature reaction of boron halide with ammonia: BCl3 + NH3 → BN + 3HCl ...
Chlorotrimethylsilane, also known as Trimethylsilyl chloride is an organosilicon compound (silyl halide), with the formula (CH3)3SiCl, often abbreviated Me3SiCl or TMSCl. It is a colourless volatile liquid that is stable in the absence of water. It is widely used in organic chemistry. Trimethy...
Though table salt may be what comes to mind when you think 'sodium,' it is actually a compound, meaning it has more than one component. Table salt is sodium chloride, and is made up partly of sodium atoms and partly of chlorine atoms. ...
What is the molar mass of ammonia? A salt contains only barium and one of the halide ions. A 0.158 g sample of the salt was dissolved in water, and an excess of sulphuric acid was added to form barium sulphate, which was filtered, dried, and weighed. Its mass was found to be 0.124...

aWe show that PtI4 is an effective Lewis acid catalyst for the activation of terminal alkynes for hydride attack and subsequent C-C bond formation. In addition, we have shown that the activity of neutral platinum salts (PtXn) can be modulated by the halide ligands. This modulation in turn ...
