From the spectral data (1h, 13c nmr, ir, ms) you were given, identify the structure of your product. explain why you chose your particular product based on the spectroscopic data. you will not receive
full marks for determination of the unknown unless you explain why.

There is no structure, it depends on what the product contains

Explanation:

In considering a spectroscopic method of identifying a product, if the compound has hydrogen atom then the proton NMR is considered because it contains a nuclear spin.

on the other hand, if it contains carbon, whether Quaternary carbon, tertiary carbon or secondary carbon, then definitely carbon-13 NMR will be considered. and if the compound has a functional group and the group absorbs IR with a particular frequency, then IR will be used in characterizing the compound..

but if the compound when bombarded gives species of radical ion, then Mass spectroscopy will be used in identifying such compound

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
