I know different compounds have different states at room temperature because of inter-molecular forces ( dipole-dipole force, hydrogen bonding, and London dispersion forces). But how do they act on ...

Ions are very reactive for obvious reasons (i.e. Coulomb force); $\ce{Cl-}$ ions will be very quick to form an ionic bond with positive ions (unless inhibited). Chlorine atoms without reduction ($\ce{...

What I couldn't understand is, for example in NaCl, there is one Na and one Cl is needed. Because Cl needs one electron to complete it's octad. But in crystal structure, there are six Cl bonded one Na,...

Wikipedia writes: There can still exist contextual differences in leaving group ability in the purest form, that is when the actual group that leaves is not affected by the reaction conditions (by ...

For a reaction: $\ce{aA->product}$ The rate law is $\text{Rate}=-\dfrac{\mathrm d[A]}{a\,\mathrm dt} = k$ Where: $k$ is the rate constant $[\ce{A}]$ is the concentration of the reactant $\ce{A}$...

Please clear this doubt of mine?

I am just curious with the fact that our body is made of so many chiral molecules the DNA that we possess is chiral, the amino acids in our body is chiral and there are many other objects other than ...

One of the famous reactions of production of alkyl halides is the reaction of hydrogen halide with alcohols. The synthesis of the alkyl halide is different depending upon the halogens. I was taught ...

My teacher wants me to make a “ 3D accurately labeled and modeled s,p,d and f orbitals for electrons” any help pictures maybe? Due Monday!!

I couldn't find the mechanism. I thought aniline would be the final product.

I am trying to create a molecular dynamics simulation by implementing a simple version of the CHARMM potential function: How are the kb and b0 constants derived based on the length of the bond?

Guys this question is from my homework. Any thought on this?

This is probably really obvious, but I really don't understand. Why does oxygen dissolve in water when oxygen is a nonpolar molecule and water is a polar molecule? It's obvious that oxygen does ...

What atoms tends to gain electrons? Metals, nonmetals or metalliods? I tried to look this up. I need to know for class- we have a test soon. Gaining electrons is one of the key points.

What level of theory is best to use for simulating effects of varying levels of light and magnetic force on a set of closely aligned CO2 molecules (preferably 5 or more). Is there a Windows desktop ...
