is CH3CH2N or NO2 a lewis acid?
I think NO2 is a lewis acid. Is that right?
You don't have enough bonds on N on the first formula unless you intend for that end to be NH2 (H2N) in which case the C is deficient. In any case, to be a Lewis acid, something must be an electron acceptor.
no, that was how it was on the paper. how do you know which one is an electron acceptor?
I think there is two lone pairs on nitrogen for the first formula.
I'm not sure how to construct the lewis structure for NO2.

:O:=N-:O:
There's suppose to be only 17 electrons, but the one I constructed has 18 electrons.
I'm not sure if this will help me determine which one is an electron acceptor.
To determine whether CH3CH2N or NO2 is a Lewis acid, we need to understand the characteristics of a Lewis acid and identify any potential electron-deficient sites.
A Lewis acid is a species that accepts an electron pair during a chemical reaction. It typically has an incomplete octet of electrons in its valence shell or available empty orbitals. Let's examine both compounds:
1. CH3CH2N: This compound, known as ethylamine, has the structural formula CH3CH2NH2. It consists of a central nitrogen atom bonded to two hydrogen atoms and an ethyl group (-CH2CH3). Since nitrogen has a lone pair of electrons, it has the potential to donate electrons and act as a Lewis base, not a Lewis acid. Therefore, CH3CH2N is not a Lewis acid.
2. NO2: This compound, known as nitro group, consists of a nitrogen atom bonded to two oxygen atoms. Nitrogen in NO2 has a formal positive charge, indicating that it lacks one electron to achieve an octet. This electron deficiency means that NO2 has the potential to accept an electron pair, making it a Lewis acid.
Therefore, the compound NO2 is a Lewis acid, while CH3CH2N is not.
