I'm looking in ~ the E2 reactions that reaction with solid bases. However, the examples of solid bases they provided are RO- and NH2-. Indigenous what i learned in basic chemistry, the strong bases in arrenhius terms are normally the facets of the an initial 2 groups in the regular table + OH.

You are watching: Is nh2- an acid or base

In essential chemistry, what provides bases strong and why space those 2 strong?

thanks

RO- and also H2N- can't be isolated. They regularly exist as group 1 or 2 salts. They're strong bases since they're unstable through their negative charge in solution. They reduce this fee by acting as a base and accepting a proton.


A ascendancy in essential chemistry is "the weaker the base, the more powerful the conjugate acid". Therefore the conjugate acid of RO- is ROH (weak acid as such RO- is solid base). And also NH2- has NH3 as its conjugate mountain which is weak so NH2- is strong


I was looking increase the NH3 i beg your pardon is ammonia. If ammonia is a weak base, how would it be a weak acid? ns was supervisor confused.


In general chemistry you are really only taking care of aqueous solutions so that's why you spend much of your time ~ above OH- together a base.

In organic chemistry you deserve to have other solvents. They can lose protons as well. Commonly a much smaller amount than water does. If you placed these organic bases in water, the water would act choose a super solid acid and protonate lock immediately. Or the contrary they are super stong bases due to the fact that they rip the proton turn off from the water.

Do part reading about pKa values for different molecules and also functional groups. It will certainly be of enormous aid as you continue on.


I understand the pka value and such but the stamin of the conjugate base bases seems prefer a combined bag because that me. For example thiolate is thought about a weak base when thiol is slightly an ext acidic 보다 alcohol and also still very weak. Likewise stuck v RCO2-.

How would certainly i number out even if it is or not a conjugate basic is solid or weak once the acid isn't specifically strong or weak?


Look in ~ it the various other way: the conjugate acid (ROH and also RNH2) are really poor acids so the base have to be really strong.

I am taking strength to average "ability come donate or expropriate a proton" and not something to carry out with concentration
