What type of amine is shown in this picture? (a) primary amine (b) secondary amine (c) tertiary amine Explain the difference between primary, secondary, tertiary and quaternary structure proteins. Give one example of each. In terms of primary, secondary, tertiary and quaternary structures, ...
The shape of a molecule is determined by the distribution of the nuclei of the atoms making up the compound around the central atom. This distribution is determined by the repulsion of the different electron groups. These groups are either bonding electrons or nonbonding electrons. According to ...
Aniline is an organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the simplest aromatic amine. It is an industrially significant commodity chemical, as well as a versatile starting material for fine chemical synthesis. Its main use is...
On performing a reaction between (1H-benzimidazol-2-ylmethyl)-N-phenyl amine (H2L) and copper(II) acetate in methanol, a green "paddle-wheel" copper(II) complex, [Cu2(CH3COO)4(H2L)2] (1), was separated after about 5min. The two Cu atoms are separated by 2.852 and bridged by ...
2-Phenoxyethanol, known early as ethylene glycol monophenyl ether, is a high-boiling, oily liquid that is moderately water-soluble. At present, there has been a lot of research on the synthesis and use of this substance. Due to its excellent properties, it has been widely used in scientific...
The SAM spacer is normally a hydrophobic alkyl chain of different carbon length, with or without phenyl rings. It provides structural support and determines the packing density and orientation of the molecules. Terminal Group The SAM tail is either an electron rich group such as carbazole, dibenzo...
The synthesis of organosulfur compounds via a metal-free approach using a variety of sulfur sources, including thiophenols, disulfides, sulfonyl hydrazides, sulfonyl chlorides, elemental sulfur and sulfinates, is discussed. Non-conventional strategies, which refer to the development of thioether ...
When a species is donating a pair of electrons to a hydrogen (more specifically, a proton, H+) we call it a base. This post attempts to address one of the most vexing question to students of organic chemistry. What are the factors that make a good nucleophile? For our purposes, there...
A drug, C14H19NO2, chemically related to amphetamine, that acts as a mild stimulant of the central nervous system and is used in its hydrochloride form to treat attention deficit hyperactivity disorder and narcolepsy. Amphetamine The racemic freebase of 1-phenylpropan-2-amine; an equal parts mi...
Aniline, a foundational chemical in the dye and pharmaceutical industries, is characterized by its direct linkage of an amino group to a benzene ring, making it a primary aromatic amine. This structure imparts distinctive chemical properties, such as enhanced reactivity with electrophiles due to the...
