Anew chemist moved into an industrial lab where work was being done on oxygenated gasoline additives. among the additives that had been tested, she found an old bottle containg a clear, pleasant-smelling liquid that was missing its label. she took a quick 1h nmr spectrum (shown below) and was able to determine the identity of the compound without any additional information. propose a structure for this compound. (hint: this is a very pure sample.)
