  • question_answer Which kind of isomerism is possible for 1-chloro-2-nitroethene [J & K 2005]

    A) Functional group isomerism

    B) Position isomerism

    C) \[E/Z\] isomerism

    D) Optical isomerism

    Correct Answer: C

    Solution :

    \[\underset{\text{1-chloro-2-nitroethene}}{\mathop{{{O}_{2}}NHC=CHCl}}\,\] For highly substituted alkenes \[E\] and \[Z\] system of nomenclature is used, which is based on a priority system developed by Cahn, Ingold and Prelog.
