Chemistry Question - Acid/Base

[kmk0984]

Hello, this might be straight forward but I got really confused with this one.

What is conjugate base and conjugate acid?
Which side of equilibrium will be favored?

NaH + CH3CH2OH <--->


I am not sure if it would be (CH3CH2O- + NaH2+) or (CH3CH2NA + H2O)

can someone please help me?

Thanks

i think that we should get CH3CH2O- and Na+ and H2.

NaH2+ and CH3CH2Na will NOT form

NaH is a very reactive and acts like Na.

NaH + CH3CH2OH ---->CH3CH2ONa + H2

NaH is a strong base and acts like Na.

NaH + CH3CH2OH ---->CH3CH2ONa + H2

He asked for a conjugent base and acid. CH3CH2O- is the conjugent base.
NaH2+ is the conjugent acid.

CH3CH20Na is not an acid base reaction.

I disagree, I think NaH will rip the entire Oxygen off. Just IMO, but I am somewhat sure. NaH acts like H with 2 electrons on it, Insanely strong base, it's like 2 electrons floating around (that must be nucleophilic).
Product will be like a gringard.
Something like CH3CH2CH2- +Na
i think the second choice that the OP had.
GOOD LUCK

Ok, just reread the question, what I said only applies if you have NaH excess.
NaH (pKa of like 50, an estimate) acts as a base and takes the proton off the alcohol. That's it.

NaH is a strong base and acts like Na.

NaH + CH3CH2OH ---->CH3CH2ONa + H2

agreed
the alcohol is the most acidic thing, so it is going to loose a proton.

Alcohols react with active metal (Na is the active metal, Na or NaH) to form alkoxides with the liberation of H2 gas
