Although catalysts are often referred to as potential methods to increase the “greenness” of a reaction, sometimes reactions yield the desired product to a sufficient degree even without any catalyst. This is often desirable because several catalysts may contain transition metals (e.g. iron, nicke...
When a periodic acid (HIO4) cleaves a vicinal diol and forms a carbonyl compound, how do you know whether it will form an ketone or an aldehyde? Why is C 4 H 10 the simplest alkene that can have structural isomers? Why does hydrosulfuric acid contain two hydrogens?
Explain why methyl vinyl ether (CH2=CHOCH3) is not a reactive dienophile in the Diels-Alder reaction.An aldehyde contains the carbonyl group. Ketones, carboxylic acids, and esters also contain the carbonyl group. What distinguishes thes...
<p>To determine which of the following compounds does not exhibit the electromeric effect, we first need to understand what the electromeric effect is.</p><p>1. <strong>Understanding the Electromeric Effect</strong>: - The electromeric effect occurs
Lubricating compositions described in FR 2 494 294 are known in particular which contain, as main constituents, a reactive polydimethylsiloxane preferably having hydroxyl end groups, a crosslinking agent preferably comprising Si—H functional groups and optionally a polycondensation catalyst....
Infrared spectroscopy is a qualitative analysis of molecules. It identifies unsaturation and functional groups present in a compound. It absorbs at wavelengths ranging from 3800 cm{eq}^{-1} {/eq} to 400 cm{eq}^{-1} {/eq}. It consists of two regions, i...
