line. Lone electron pairs are shown as twin black dots. The single electron of the “donated” hydrogen is retained in the bond between the hydrogen atom and the donor atom, meaning that it’s technically just a proton that’s donated in any given hydrogen bond. (Image credit:Thomas ...
Hydrogen bondsare intermediate in terms of strength and length when compared tovan der waal's forcesandcovalent bonds. A hydrogen bond is mainly formed between a donor atoms such as an amine, which acts as a ligand, or a lewisbaseand acceptor atom likecarboxylic acid. The larger the number...
Inset is the schematic diagram of hydrogen bonds formed between the -CONH2 in monomer AM and the -COOH on the surface of PS latex particles. The introduction of AM does not lead to an obvious change in the pH value of the aqueous dispersion solution of PS latex particles, which can ...
Describe the type and nature of the bonding that often occurs between two nonmetals. In ammonia (NH3), what type of bond is formed between nitrogen and hydrogen? Explain. Can CH3CH2CH2CONH2 form hydrogen bonds with water molecules? Explain. ...
These results indicate that an intramolecular hydrogen bond is formed between the hydroxyl and alkyl groups in the cationic ground state ofortho-cresol andortho-ethylphenol. The remarkable low-frequency shift of the OH vibration also indicates that the alkyl group acts as a proton acceptor in the...
hydrogen bond A chemical bond formed between an electropositive atom (typically hydrogen) and a strongly electronegative atom, such as oxygen or nitrogen. Hydrogen bonds are responsible for the bonding of water molecules in liquid and solid states, and are weaker than covalent and ionic bonds. The...
Hydrogen bonds are formed as a result of the attractive force occurring between a hydrogen atom which is already covalently bonded to a very electronegative atom like oxygen, fluorine, or nitrogen and another very electronegative atom like those. This other atom can be oxygen, fluorine, ...
Stabilizing intramolecular hydrogen bonds between the glucose units were made responsible for the high binding potentials of those #946;-CD derivatives that possess secondary hydroxy groups. 展开 关键词: binding constant cyclodextrin hydrogen bond methylation regioselective ...
Despite the loss of one N–H…S–O hydrogen bond owing to a competing N–H…O = C(progesterone) hydrogen bond, the quasi-hexagonal motif of the GS sheet remains intact. The adaptability of the GS frameworks to various guests is illustrated further by compound (G2SDS) ⊃ (7...
