Pentаnаl hаs the mоlecular structure shоwn belоw and MW = 86. Draw the structures of dominant fragments present in the mass spectrum (include McLafferty rearrangement). You can verify the fragmentation pattern in the mass spectrum shown below. Write on paper and submit after the test with all the other answers.
