methanol is more acidic than ethanol why?


methanol is more acidic than ethanol why?

Ethoxide ion is a stronger base than hydroxide ion. Thus ethanol is a weaker acid than water. It is true for all alcohols except methanol, which is slightly more acidic than water.

Comparing methoxide and hydroxide ions, O is attached to a CH3 group in one and H in the other. CH3 allows greater surface area for the minus charge to be accommodated than H. This is true for only this case.What makes methanol (pKa 15.54) a stronger acid than water (pKa 15.74)?The pKa's that you cite are in water, where solvation and H-bonds can make a large difference so it's hard to gather any information that is of predictive value from analyzing this alone.

Why is CHF3 less acidic than CHCl3?

Why is CHF3 less acidic than CHCl3? The idea behind determining which compound is more acidic is linked to the stability of the conjugate bases. The more stable the conjugate base, the easier it is for the compound to lose a proton, the more acidic the compound. Comparing the two conjugate bases, CF3- and CCl3-. The negative charge on CF3- is stabilised by the induction effect of the electronegative fluorine while the negative charge on CCl3- is stabilised by both induction effects of chlorine and by delocalisation. This delocation can happen in CCl3- because the filled 2p orbitals of C can overlap with the empty 3d orbitals of Cl which lowers the energy. Some people call this backbonding. However F does not have empty d orbitals and this overlap cannot occur. Therefore, although the induction effect of F is stronger, the combination of induction and back bonding effect better stabilises the conjugate base in CHCl3, making it a strong...

What is the name of CH3-CH2-CHCl-COONa?

What is the nomenclature of CH3-CH2-O-Na? Well let’s say you put this into an aqueous solution like water. H2O. You would see that Na+ would leave the molecule in a flash and you would get an H+ in its place. Then it would be ethanol Answer · Organic Chemistry What is the name of CH3-CH2-CHCl-COONa? That’s a salt of an organic acid. Let's see what IUPAC blue book has to say about this: P-65.6.2.1 Neutral salts of acids are named by citing the name of the cation(s) followed by the name of the anion (see P-72.2.2.2) as a separate word. Different cations are cited in alphabetical order. Formation of salts is a functionalization and not a substitution. Thus, all retained names, both those used as preferred IUPAC names and those used only for general nomenclature, can be used without restriction. Hence, without the chloro-substituent, we could use the t...

Why is NH4OH unstable?

Why is NH4OH unstable? What do you mean by unstable? NH4OH does not really exist as such. There is NH3, ammonia, which is a weak base, meaning that in aqueous solution, only a few, typically something like 1 in 100 molecules of NH3 take a proton from H2O and become NH4+, this means a hydroxide ion OH- is left behind, together, but they are never directly joined together. NH4+ and OH- add up to NH4OH, however 99 out of 100 molecules will simply be ammonia NH3 molecules dissolved in water, forming hydrogen bonds with water. However water molecules a bit more attracted to other water molecules than they are to ammonia molecules, So ammonia molecules from a solution of ammonia quite easily escape into the air, which is why you can smell ammonia solution so easily and the solution always has a tendency to become less concentrated over time (perhaps this is what you meant).
