Question
FOR EACH SPECTRUM BELOW,
• IDENTIFY (ASSIGN) THE MOLECULAR ION PEAK AND THE MOLECULAR WT OF THE COMPOUND. ( KEEP IN MIND THAT SOMETIMES THE MOLECULAR ION MAY NOT BE PRESENT, ESPECIALLY FOR LARGE AND BRANCHED CHAIN MOLECULES WITH NO RINGS SINCE THEY CAN FORM STABLE CATION FRAGMENTS)
• IDENTIFY THE BASE PEAK AND DRAW STRUCTURE FOR IT ( ASSIGNING THE PEAKS).)
• ASSIGN STRUCTURES FOR OTHER PROMINENT FRAGMENTS IF POSSIBLE
• BASED ON THIS, SUGGEST A STRUCTURE FOR THE COMPOUND THAT IS CONSISTENT WITH THE DEGREE OF UNSATURATION OF THE COMPOUND
INDICATE THE BONDS THAT FRAGMENT, RESULTING IN THE OBSERVED MASS SPECTRAL FRAGMENTS
