2-4. not partial please Problem 3 An unknown substance shows a molècular ion peak at m/z= 170 with a relative intensity of 100. The M+ 1 peak has an intensity of 13.2, and the M+2 peak has an intensity of 1.00. What is the molecular formula of the unknown? Can you propose a structure? Problem 4: An unknown hydrocarbon has a molecular ion peak at m/z = 84, with a relative intensity of 31.3. The M+ 1 peak has a...
A non-branching ether has a molecular ion peak at m/z=102 and another significant peak at m/z=57. Draw the structure of the molecule. You do not need to show the hydrogen atoms, but you may want to place the carbon atoms in a zigzag pattern to make it easier to count how many you've drawn.
1. An unknown hydrocarbon has a molecular ion peak at m/z 84 with a relative intensity of 31.3. The M+1 peak has a relative intensity of 2.06 and the M+2 peak has a relative intensity of 0.08. What is the possible molecular formula of the compound?
