what are the major absorptions in functional group region for each compound One 212 C) A compound must have an appropriate number d) ) All ot of elettroes in the cycic arrangement of 19. 3. Consider the it spectrum bilow is this the spectrum Describe the soiy 20. What are the major absorptions in functional group region for each compound?(10) N H : 1. How do the isomers of molecular formula C, H,0 differ in IR Spectra? ( at least show the structures of two isomers, show peaks in functional group region and which peaks will help differentiate them to justify your answer ) (10) 22. Draw the most stable radicals that can result from cleavage of a C-H bond in each molecule.(20)Explanation / Answer
20. A is an alkene, thus, it will show major absorption of alkenes i.e., a strong peak at 3010-3100 cm-1 due to =C-H stretch and a C=C stretch at 1620-1680 cm-1.
B is an alcohol, hence will show a strong broad OH peak from 3300-3600 cm-1 and C-O at around 1000 cm-1.
C is a ketone, which will show a strong C=O peak at 1715 cm-1.
D is a primary amine, hence will have two medium N-H stretching bands at 3300-3500 cm-1. It will also show N-H bending at 1600 cm-1 and a medium C-N stretch at 1600 cm-1.
