How could spectroscopy be used to support that the below reaction occurred? Choose all that apply. NaCCH Choose one or more: Use IR; the starting material has a sharp narrow peak at 3300cm1, but the product does not. Use IR; the product has a sharp narrow peak at 3300cm1, but the starting material does not. IR will not be useful as no detectable change in the spectrum will occur. Use IR; the product has a strong broad peak at 2200cm1, but the starting material does not. Use IR; the starting material has a strong broad peak at 2200cm1, but the product does not
