Why is NaNH2 a base?
Why is NaNH2 a base?
NaNH2 is a strong base, intended to be strong enough to deprotonate the alkyne (pKa u2248 25). But that would also make it strong enough to deprotonate the alcohol (pKa u2248 16, close to water), and because the alcohol is a stronger acid, it would be deprotonated first.
Is NaNH2 a strong or weak base?
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).

Is NaNH2 a strong base than NaOH?
Yes, NaH is a stronger base than NaOH. NaH is better at deprotonation when compared to NaOH.
Is NaNH2 a basic salt?
Sodium amide, NaNH2, is a salt that contains the very strong base amide ion (NH2-).
Is NaNH2 a base or acid?
strong base
Why is NaNH2 a strong base than NaOH?
Why ? 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.
Is Sodium amide a strong base?
Sodium amide is a strong base. For example, it can be used as shown here to deprotonate a terminal alkyne such as propyne to produce an alkyne anion.
Why NaNH2 behaves as a base in liquid NH3?
Why? Sodium amide would act as a base in liquid ammonia because it would dissociate to produce the amide species, . This amide ion have tendency to accept proton, therefore it is a base.
Is NaNH2 strong base?
