Explain how hydrodewaxing, hydrocracking and hydroisomeriztion processing take place In base oil refining and also describe how aromatics (low volatile products) are converted to high quality base oil.
modify the 3 molecules so that they show the form that is dominant at physiological pH: formic acid, acetylsalicylic acid (aspirin), and citric acid
The mass spectrum of an organic compound shows the relative abundances of M to be 44.42% and M 1 to be 10.57%. Assuming the peaks are caused by 12C and 13C isotopes
The absence of an alkene C=C IR stretch is definitive evidence that a compound lacks an alkene functional group.
