![]() Trans coupling (range :11 to 19 Hz) is greater than cis coupling (range: 5 to 14 Hz). For coupling the two hydrogens must have different chemical shift. Distinction between cis and trans isomers Trans coupling is greater than for cis. Why are alkenyl hydrogens trans instead of CIS?.How are alkene carbons deshielded in nuclear magnetic resonance?.Why are NMR spectrums different for CIS and trans isomers?.How are alkenes different from other carbons in NMR?.What is the chemical shift for carboxylic Proton?.What is the difference between cis-trans and EZ?.
