The molecular weight of a pure compound is determined from its chemical formula and the atomic weights of its elements. The atomic weights of the elements found in organic substances are C = 12.011, H = 1.008, S = 32.065, O = 15.999, and N = 14.007. Example: The molecular weight of...
Molecular formula =C(5)H(10) Degree of unsaturation =(C(n)+1)-(H(n))/(2) where, C(n)=number of carbon atoms H(n)=number of hydrogen atoms =(5+1)-(10)/(2)=1 Compound A will be either alkene or cyclic hydrocation. Since, A is undergoing ozonolysis he
