Question

bony incorrect x incorrect How could spectroscopy be used to support that the below reaction occured? Choose all that apply. NaCECH DMSO CH Use UV-vis: the product would show an absorbance at a longer Amax from that of the starting material Use UV-vis; the product would show an absorbance at a shorter A from that of the starting material UV-vis will not be useful as no major change in A would occur Use IR: the starting material has a narrow peak at 2200 cm 1 but the product does not v Check Answer Q View Solution Hint Progress 19 20 21 22 23 24 25 27 Exit Activity

Explanation / Answer

1. uv.vis, spectum shifts to longer wave lenth due to incerese in conjugation and unsaturationn in sysytem

4. product shows narrow peak at 2200.due to C-C triplebond strecthing.

7. product show peak at 3300. that is sp hybridised C-H streching vibrations.
