Title: Hydrazine N2H2(?)
Post by: Monty on May 05, 2005, 06:42:46 AM

I have been asked to draw the elctron dot diagram for hydrazine with the formula given as N₂H₂. I thought the formula should have been N₂H₄.

What is the correct chemical (and common) name for N₂H₂?

Please confirm the correct electron dot structure for them both.

You are correct in thinking the formula for hydrazine is N2H4.  I think someone might have made a mistake in the question.

P.S.  To my knowledge there arent any chemicals with the formula N2H2.  I can only imagine that it would be terribly reactive and unstable.  If you post an electron dot structure for hydrazine, I'll let you know how it looks.

Yes, that is a typo.  Hydrzine is basically just a di-amine H2N-NH2.

 We are using N2H2 in the owen for soldering. its only mixture N2 and H2 in one space, ist not chemical substance.

Not especially unstable, but usually made in situ from hydrazine and peroxides or chloramine-T etc, HN=NH is diimine.

Can be used in organic chemistry as a reducing agent in its own right, to e.g. convert olefins to alkanes stereospecifically in an electrocyclic reaction.
