Is this an amine? CH3-CH2-NO2

Question

CH3-CH2-NO2

I don't think it is, because there is no lone pair on the N right?

Answer 1

no it is not an amine it forms amine when reacted with water in the presence of HCl

                          

CH3CH2-NO2+H2O---->CH3COOH+NH2OH.HCL

nitroethane                       ethanoic  acid         hydroxylamine hydrochloride

Answer 2

It is a nitro compound: nitroethane in fact.

Amines contain the -NR2 group where R can be hydrogen or alkyl groups.

So:

-NH2 is a primary amine

-NHR is a secondary amine

-NR2 is a tertiary amine.

Nitro compounds will reduce to amines on treatment with a suitable reducing agent (not just an acid): tin and concentrated HCl is commonly used for this reaction.

Answer 3

You're correct.It's a nitro compound.

It's only an amine if it has one or more non-aromatic carbons bonded to a neutral nitrogen, and the other groups attached (if any) are all hydrogens.
