2-333 Which of the following pure compounds can form hydrogen bonds? Which can form hydrogen bonds with water?(a)(CH,CH2)2NH(b)(CH, CH2),N(c)CHCH2CH2OH(d) (CH_3CH_2CH_2)_2O(e) CH_3(CH_2)_3CH ,(f) CH_2=CH-CH_2CH_2(g)CH, COCH,(h)CH, CH COOH(i) CH_3CH_2...
aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, so H2O can form four hydrogen bonds. [translate] ...
In our previous work we have shown that the hydrogen atomic charges derived from infrared intensities can be used to evaluate the possibility of forming hydrogen bonds. In particular, infrared atomic charges predict that CH bonds in sp hybridization can act as proton donors in molecular complexes...
The hydrogen bond is a type of electrostatic force of attraction between a hydrogen atom(which is covalently bonded with an electronegative atom) and another electronegative atom with lone pair( for example oxygen in ketone).Hydrogen bond is...
a) Hydrogen bonds b) Phosphodiester bonds c) Covalent bonds d) Ionic bonds e) Peptide bonds DNA molecule: The 2'-deoxyribonucleic acid or known as DNA is an example of a nucleic acid that is considered ...
aBecause insulin has amino groups and hydroxy groups, it can form hydrogen bonds with PEG or HTCC, which strengthened the crosslinked network and slowed drug release. 由于胰岛素有氨基和羟小组,它可能形成氢键与钉或HTCC,加强被交互相联的网络并且减慢药物发行。 [translate] ...
