Typewritten please because I have a poor eyesight that's why I'm having a hard time understanding handwritten answer especially cursive. Thank you for understanding.How could spectroscopy be used to support that the below reaction occurred? Choose all that apply. H₂C CH excess HCI H₂C. CI CI CH3 Choose one or more: OUV-vis will not be useful because no change in Amax would occur. O Use UV-vis; the product would not show an absorbance in the spectrum range due to a shorter Amax from that of the starting material O Use UV-vis; the product would show an absorbance at a longer Amax from that of the starting material. O IR will not be useful as no detectable change in the spectrum will occur. O Use IR; the product has a sharp narrow peak at 3300 cm-¹, but the starting material does not. O Use IR; the starting material has a sharp narrow peak at 3300 cm-1, but the product does not. O Use IR; the product has a strong broad peak at 2200 cm-¹, but the starting material does not.
