Indicate those of the following statements that are correct for a liquid consisting purely of the compound $^{13}$CH$_3$OH at room temperature. The carbon-13 spectrum will be a 1:2:1 triplet. The proton NMR spectrum will be a 1:1 doublet and a broad singlet. The broad singlet in the proton spectrum is due to the exchange of protons among methanol molecules. Because of the oxygen, the IR spectrum will have a strong band around 1750 cm$^{-1}$. This compound will absorb in the visible region, and will therefore be coloured. The mass spectrum should have a peak at mass 15.
