In organic chemistry, an alkyl substituent is an alkane missing one hydrogen. ... Typically an alkyl is a part of a larger molecule. In structural formula, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula CH3−....
What physical test can be performed to verify if a liquid is pure or not? What test could be performed to distinguish the following pair of compounds? CH3CH2CH2CH3 and CH2=CHCH2CH3 What are the two methods used for testing water in chemical compounds?
In chemistry, there are lots of compounds that can arrange themselves in different arrangements in which they are more stable. These arrangements can be based on the orientation of groups or spatial arrangement of groups around a double bond. These arrangements lead towards isomerism....
When placed in a solution with a pH of 9, litmus will be ___. Determine the pH of a 0.20M CH3NH3I solution. Calculate the pH of a 0.100 M solution of NH4CN. (KaNH4+ = 5.6 x 10^-10; KbCN- = 1.6 x 10^-5) If the pH of a solution is 4, what is the pOH? ...

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...
Chemistry is the study of substances; their properties, structure, and the changes they undergo. Micro-macro: the forest or the trees Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. But when we look at matter in bulk, we...
4-Dimethylaminopyridine (DMAP) is a derivative of pyridine with the chemical formula (CH3)2NC5H4N. This colourless solid is of interest because it is more basic than pyridine, owing to the resonance stabilisation from the NMe2 substituent. Chemical Properties DMAP (m.p. 112-113°C) and PPY...
