—Data from mass spectra to: i suggest possible structures of a simple organic compound given accurate relative molecular

Be able to use data from mass spectra to: i suggest possible structures of a simple organic compound given accurate relative molecular masses ii calculate the accurate relative molecular mass of a compound, given accurate relative atomic masses to four decimal places.

Use —data from mass spectra to: i suggest possible structures of a simple organic compound given accurate relative molecular to connect the rule to the data and decision in the question.

This matters because —data from mass spectra to: i suggest possible structures of a simple organic compound given accurate relative molecular determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —data from mass spectra to: i suggest possible structures of a simple organic compound given accurate relative molecular to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Data from mass spectra to: i suggest possible structures of a simple organic compound given accurate relative molecular is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
