Then, the influence of valence of triel atom on the triel bond has been theoretically investigated in thirty-two complexes composed by Lewis acids TrHX/TrH2X (Tr = Ga, In; X = F, Cl, Br, I) and Lewis base H2Y (Y = O, S) molecules at MP2/augヽc﹑VTZ(PP) theory level. ...
a(3) molecular space configuration: generally speaking, the more symmetrical type space of molecules, and the intermolecular forces smaller. [translate] aCompare the magnitude of intermolecular forces of H2O and O2: [translate] aThe hydrogen bond is a weak bond,but than van der Waals force is ...
Which molecules catalyze covalent bond formation between fragments of DNA: A. Helicase B. Ligase C. Polymerase D. Primase E. Nuclease What are the steps of protein synthesis starting with DNA? What are the two cell structures involved in protein synthesis?
Liquid:(random molecular arrangement), partially, there is hydrogen bond between two molecules of water, so there is some kind of structure Constant random motion No definite shape Little strength, 注意!对于有hydrogen bond(water)的是little intermolecular force, 不是intramolecular (can be...

6 C_2H_4andC_2H_2are unsaturated hydrocarbons.Which statement is correct regarding these two molecules? C A Both C2H4 and C2H2 are polar molecules. B Both C2H4 and C2H2 have the same shape. C C2H4 has more o bonds but fewer t bonds than C2H2. D The carbon-carbon-hydrogen bond angle...
What molecules contain the strongest polar covalent bond? Molecules containing fluorine (F) and oxygen (O) typically have the strongest polar covalent bonds. For example, the bonds in compounds like hydrogen fluoride (HF) and water (H2O) are known for their high polarity due to the electronegati...
Carbon monoxide contains covalent bonds as their atoms share the electrons so that their valence shell is filled but weak intermolecular forces join their molecules together which can be easily broken and thus they have a low melting point.Carbon dioxide also has a low ...
