# Does dihydroimidazole show geometrical isomerism?

Does dihydroimidazole (above) exhibit geometrical isomerism? Does the fact that the lone pair is involved in conjugation with a double bond affect anything?

As far as I know, it does not exhibit geometrical isomerism. However, one of my colleagues pointed out that the two nitrogens' lone pairs and hydrogens can adopt cis and trans configuration with respect to each other.

• @schrodinger_16 although Mithoron is quite rude, he is right. Nitrogens are somewhere between $sp_2$ and $sp_3$ hybridization. If you look carefully at $sp_3$ nitrogen, you will see that nitrogen's hydrogen can be in cis-trans configuration...(hope to be clear even if I am wrong) – user43021 Apr 28 '18 at 15:23
