Which is more basic hydroxide or methoxide?
Methoxide is a relatively unhindered base, as is hydroxide. But as explained above, methoxide experiences induction whereas hydroxide does not. So one would expect methoxide to be a better nucleophile than hydroxide because it is a stronger base than hydroxide and still remains unhindered.
Which is more basic sodium ethoxide or sodium hydroxide?
Conjugate acid of ethoxide (-OC2H5) is ethanol and that of OH- is H2O. Now water is more acidic than ethanol. So it will remain ionise more than that of ethanol. Thus sodium ethoxide is more basic than NaOH.
Which is more basic LiOH or NaOH?
Mostly Basic character depends on the ease of donating OH− ions. Among NaOH and LiOH basic character of NaOH is more as the bond between Na and OH is weaker than the bond between Li and OH. Hence NaOH is more basic than LiOH.
Which is stronger NaNH2 or NaOH?
NaNH2 is more basic than NaOH because O has more electronegativity than N resulting in more attraction of electrons towards it during sharing of electrons. therefore bond between O and H is easily breakable as compared to N and H. therefore this concludes that NaNH2 is more basic than NaOH.
Why is Methoxide weaker base than hydroxide?
CH3O- is a weaker base because we call CH3 an electron releasing group only when attached to an -I group, but O- is an extremely strong +I group so CH3 isn’t contributing much increasing negative charge on O- . Stronger the acid, weaker is it’s conjugate base. Now water is more acidic than methanol ( Yes it is true) .
Is sodium methoxide a strong base?
Regarding the first question, sodium methoxide is a strong base (pKa = 15.5). It can also act as a nucleophile, but it is a much “better” base than nucleophile so if added to a reaction with any kind of acidic hydrogen, it will abstract it instead of performing a nucleophilic attack.
Why is Methoxide a strong base?
Methoxide (CH3O−) is the conjugate base of methanol. Methanol is very weak acid (e.g. its dissociation constant is very small), so its conjugated base is very strong.
Which is more basic NaOH or KOH?
NaOH is stronger base than KOH. The reason is the dissociation power of NaOH is greater than KOH. When we put NaOH in water, it quickly gets dissociated into Na+ and OH- ions. Whereas in the case of KOH it’s dissociation( breaking up into ions ) energy is quite low as compared with NaOH.
Which is better base OH or RO?
Answer: Alkoxide means RO-. R is any alkyl group. So, As Alkoxide has now higher tendency to donate electrons as compared to normal hydroxide, so Alkoxide is a stronger base than normal hydroxide ions.
Which is more basic than hydroxide ion?
Hydride ion (H−) is a stronger base than hydroxide ion (OH−).
