is oh or sh a better nucleophile?

SH- anion is more nucleophilic than OH- anion as the negative charge is more stable on oxygen atom than sulphur, because of higher electronegativity of oxygen.

Here is the difference Between OH and HO: HO is a molecule containing positive Hydrogen Oxygen atoms i.e it is a cation. ... Both are ions, HO+ is Hydroxide, OH- is Oxyhydride. Both are acceptable and the only difference is about the charge on oxygen.

HClO3 has less oxygens and, therefore, pulls less electrons from the O-H bond. Originally Answered: Why is HClO3 a stronger acid than HClO2? The more electron-drawing the group that bonds to OH group is, the more polar O-H bond is, which makes it easier to electrolyse, which mean it is more acidic.

1 Answer. Due to greater electronegativity of F over Cl, F forms stronger H-bonds as compared to Cl. As a result, more energy is needed to break the H-bonds in HF than in HCl and hence the b.p. of HF is higher than that of HCl. Consequently, H-F is liquid while HCl is a gas at room temperature.

Water is neutral whereas ammonia is a weak base (even less acidic). ... Therefore, NH2- is a stronger base. OH- is better leaving grp because NH2- is stronger base.

CHCl3 is a stronger acid among them. The acidic strengths of the other two alkyl halides be compared their inductive effects.

A polar aprotic solvent like acetone does not hydrogen bond to ethoxide ion to a significant extent. So the ethoxide ion is almost a "bare" nucleophile. It is better able to attack the substrate and is therefore a stronger nucleophile.

so the ester is more reactive than the acid. ... Since the -OR group is a stronger electron donor (resonance) than the alkyl group of the ketone, the ester is less reactive than the ketone... so we get : (b) The aldehyde, carboxylic acid and ester will be reduced to the same product, benzyl alcohol.

HCl is a stronger acid than HF because fluorine is more electronegative than chlorine.

The “OH” part of the molecule is the alcohol functional group (not to be confused with the hydroxide ion, OH-). The H on the OH group is weakly acidic because the strongly electronegative oxygen pulls electron density away from the H, making it more like an H+ ion.

I⁻ is a better nucleophile than F⁻ in polar protic solvents. F⁻ is a better nucleophile than Br⁻ in polar aprotic solvents. ... This creates a "shell" of solvent molecules around the nucleophile. The nucleophile has to push this shell of solvent molecules out of the way to attack the carbon bearing the leaving group.

The nucleophiles are almost unsolvated, so it is much easier for them to attack the substrate. Nucleophiles are more nucleophilic in aprotic solvents. So, SN2 reactions "prefer" aprotic solvents.

What it's used for: NaNH2 is a strong base and excellent nucleophile. It's used for deprotonation of weak acids and also for elimination reactions. ... As a strong base, NaNH2 will deprotonate alkynes, alcohols, and a host of other functional groups with acidic protons such as esters and ketones.

HBr, HF HBr is the stronger acid because Br is larger than F. Thus, the H-BR bond is weaker than the H-F bond and Dr- is more stable than F-.

Alkyl halides can undergo two major types of reactions - substitution and/or elimination. The substitution reaction is called a Nucleophilic Substitution reaction because the electrophilic alkyl halide forms a new bond with the nucleophile which substitutes for (replaces) the halogen at the alpha-carbon.

What it's used for: NaNH2 is a strong base and excellent nucleophile. It's used for deprotonation of weak acids and also for elimination reactions. Similar to: LDA (lithium diisopropylamide). The NH2- anion is the conjugate base of ammonia (NH3).

The nucleophile will attack the mercuronium ion at this time. Therefore, the nucleophile attacks the more substituted carbon because it retains a more positive character than the lesser substituted carbon. Stereochemically, oxymercuration is an anti addition.
