what is the techincal name for hydrazine?

Answer 1

You've got it - it is simply hydrazine for the formula NH2-NH2.
It turns out though that hydrazine can also refer to the general functional group of NH2-NH-R where R can be a variety of groups. For example a common hydrazine is 2,4-dinitrophenyl hydrazine, where the R group is a 2,4-dinitrophenyl group.

Hydrazines react with ketones and aldehydes (C=O containing molecules) to give what are known as hydrazones.

Answer 2

Hydrazine is the chemical compound with formula N2H4. This species is widely used in chemical synthesis. It is perhaps best known as a component in rocket fuel. Hydrazine is also found in tobacco products.

Conceptually, hydrazine arises via coupling a pair of ammonia molecules by removal of one H per molecule. Each H2N-N subunit is pyramidal. The N-N distance is 1.45 Å. The molecule adopts a gauche conformation, as seen also in hydrogen peroxide. The rotational barrier is twice that of ethane.

Hydrazine has a liquid range and density like water's. It has basic properties comparable to ammonia but 15-times weaker. It can be di-protonated only with difficulty:[1]

N2H4 + H+ → [N2H5]+ K = 8.5 x 10-7
(for ammonia K = 1.78 x 10-5)

[N2H5]+ + H+ → [N2H6]2+ K = 8.4 x 10-16

Answer 3

Hydrazine is the official name. I do not believe there are any other common names.

Answer 4

that is the technical name
