Answer 1

Answer #1

The compound is cis-2-pentene (Top Left compound)

1659 cm-1, C=C stretching for disubstituted (cis)

1458 cm-1, C-H bending in -CH₃

698 cm-1, strong, C=C bending for disubstituted (cis)

I have also attached standard IR spectrum as well as bending vibrational data table for your kind consideration below!

molecular formula is not given No forma For the IR spectrum, each major signal should be identified by wavenumber (stretching. frequency) and assigned to the corresponding bond. A conclusion about functional groups should also be drawn from the spectrum. In the C-NMR spectrum, the chemical shift of each signal should be noted and a structural assignment should be made. In 'H-NMR spectrum, the chemical shift, integration, and splitting pattern for each signal should be noted and a structural assignment should...
