Write the Lewis structures of both isomers with the \(formula {C_2}{H_7}\;N. \)

Amines are organic compounds that have amino groups included in the hydrocarbon chain.

Nitrogen is a trivalent atom and can contain up to three bonds, whether those are three single bonds or one double and single, or just a triple bond

If it contains 4 bonds around it, it becomes a cation because it has one electron less in its valence shell (4 instead of 5).

The first isomer is the picture on the left

That isomer has an\(N\)atom in the middle and two methyl groups bonded on each side.

Since it's a trivalent atom, one\(H\)atom must be assigned to its structure.

Also, it contains one lone pair of electrons in the neutral state.

The second isomer is the picture on the right.

That isomer has an\(N\)atom at the end of the ethyl chain. Therefore, it has one bond already.

Since\(N\)is a trivalent atom, it means that\(2H\)atoms need to be assigned to their structure.

Also, it contains one lone pair of electrons in a neutral state.
