If rotaxanes (where a cyclic molecule remains threaded on a linear one because of bulky capping groups on the thread) are molecules, what about pseudorotaxanes, where there are no end caps and the threading is merely statistical, or held in place by weak interactions? One can clearly enginee...
解析 A compound is a substance form two or more elements chemically united in fixed proportions. A molecule is a group of atom that can take part in a chemical reaction.结果一 题目 what's the difference between a compound and a molecule?rt 答案 A compound is a substance form two or ...
Water is made up of two different elements, 2 hydrogens and 1 oxygen, so H2O is a compound. Two oxygen atoms (O2) are two elements, but they are the same element, so O2 is a molecule. Iron oxide (Fe2O3), or rust, is made up of two different elements, 2 irons and 3 oxygens...
you wouldn’t consider it a molecule, as it is in fact a huge lattice network of individual sodium chloride compound particles, without a clear number of atomic nuclei. The same thing is true if you look at a drop of water; you aren’t looking at a molecule of water, but rather a h...
A molecule, such as H20, is the smallest unit of a compound that maintains the characteristics of that compound. A compound often looks and behaves differently from its constituent elements. Consider a water (H2O)molecule, which is made up of two hydrogen atoms and one oxygen atom. Both hydr...

The molecule is in a flat or planar hexagon ring. The molecular orbital description involves the formation of three delocalized π orbitals spanning all six carbon atoms, while the valence bond description involves a superposition of resonance structures. It is likely that this stability contributes ...
Classify the following compound as aromatic, antiaromatic, nonaromatic? How can you determine if a molecule is aromatic or not? Which of these species is an aromatic compound? A. C5H10 B. C2H2 C. C6H4Br2 D. C6H12 Deduce if the given compound is aromatic? For any compound that is not ...
I conducted a flame test on that compound. had it been a copper compound it sohuld have flamed green. It flamed orange/yellow, which is what sodium does. So.. unless yet again my logic is flawed here, this cant be a copper compound. another thing that caught my attention is this. ...
What intermolecular force is responsible for the attraction between an ion and a polar molecule? What is a tetrahedral molecule? Identify the bonds in the compound CNH5 as polar or non-polar. Is SeH2 polar or nonpolar? Are hydrogen bonds polar or nonpolar?
