Interpretation:
The strongest bond has to be identified from C=O bond in an ester (1735 cm-1) or the C=O bond in a saturated
Concept introduction:
Spectroscopy:
It is study of the interaction of matter and
IR frequency (cm-1):
It is the number of wave crests that pass by a given point in one second frequency has units of hertz (Hz).
Stretch vibrations:
It is a vibration occurring along the line of the bond a stretching vibration changes the bond length.
Bending vibrations:
It is a vibration that does not occur along the line of the bond, bending vibration changes the bond angle.
Given information:
The IR value is given below,

- structures are fragments of major product of dehydration reaction of 2-methylbutan-2-ol. need to know why some of them have base peaks of 97. B and D have base peaks of 97.1, and A and C have peaks of 57.1arrow_forwardThe mass spectrum of 1-ethyl-1-methylcyclohexane shows many fragments, with two in very large abundance. One appears at m/z = 111 and the other appears at m/z = 97. Determine the identity and structure of each of these fragmentsarrow_forwardThe diasteromers of 4-t-butylcyclohexanol that you make can be distinguished by the splitting patterns of the proton attached to the carbon bearing th OH group. This is due to the fact that the H that is axial is a triplet of triplets because it is coupled to to sets of non-eqivalent protons, while the equatorial H is coupled to 4 equivalent hydrogens and is a pentet.
