Witryna1 lip 2024 · Furthermore, many alkenes can take two geometric forms: cis or trans. The cis and trans forms of a given alkene are different molecules with different physical … In organic chemistry, a Schiff base (named after Hugo Schiff) is a compound with the general structure R R C=NR (R = alkyl or aryl, but not hydrogen). They can be considered a sub-class of imines, being either secondary ketimines or secondary aldimines depending on their structure. The term is often synonymous with azomethine which refers specifically to secondary aldimines (i.e. R−CH=NR' where R' ≠ H).
