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] ...
What is a type of chemical bond involving the sharing of electrons between atoms in a molecule, especially the sharing of a pair of electrons by two adjacent atoms? Which type of bond must be broken for water to vaporize? a) Ionic bonds b) Polar ...
When hydrogen atoms interact with each other, they form a diatomic molecule called hydrogen gas. What type of bond holds two hydrogen atoms together in hydrogen gas? Which molecule can form hydrogen bonds with water but not with another molecule of itself? And why? (Hint: draw out the Lewis...
Based on interaction energies obtained from ab initio calculations for complexes of these molecules with water, the oxygen atoms can be classified as rather weak hydrogen-bond acceptors; nitrogen atoms present in the same fragment exhibit much stronger interaction energies. The ab initio results are ...

What is the molecule that contains the strongest polar covalent bond? Hydrochloric acid (HCl) contains one of the strongest polar covalent bonds, with a large electronegativity difference between hydrogen and chlorine atoms, resulting in a strong dipole moment. ...
aHydrogen bond. A strong secondary interatomic bond that exists between a bound hydrogen atom (its unscreened proton) and the electrons of adjacent atoms. 氢键。 存在一定的氢原子之间它未用屏幕保护的氢核和毗邻 (原子电子) 的强的次要interatomic债券。[translate] ...
