Transcript of Human Molecular Formula
Badarla Sandeep
A Text book of
Human'sMolecularFormulae
Preface:
This book is entirely based on organicnomenclature.This book is written with the aims that every personshould have their individual "Molecular Formulae".In this bookevery topic have been dealt to the point in a simple andunderstandable language.Things have been explained where everpossible.A good number of illustration examples with answers isalso provided in this book.This helps the students in devolopingtheir resoning skills in "Organic Nomenclature".
As every organic compound has its ownname and molecular formula.This text book helps in framing themolecular formula of each individual.Hope this text book would beintresting and meet the needs who want to know how a personcan be given a molecular formula.

Before discussing about Molecular formulae of a person lets build up our basicsabout "Oragnic Nomenclature".
1.What is Organic Chemistry? Organic Chemistry is a chemistry involving thescientific study of structure, properties, compsition of Carbon based componds,Hydro Carbons and their derivatives.These compounds may contain any numberof other elements, including hydrogen, nitrogen, oxygen, the halogens as well asphosphorous, silicon and sulphur.
2.Why is Organic Nomenclature Necessary? Organic chemistry is a vast branch as millionsof organic compounds are already known and thousands of new compounds arebeign added to this list every year.In order to facilitate the study of such largenumber of compounds.Therefore it is necessary to classify the organiccompounds. In order to classify this organic compounds the term "Nomenclature"comes into picture.
3.What is nomenclature? Nomenclature means the assesment of namesto the organic componds.The naming of organic compounds is an importantaspect in the study of organic chemistry as their number is very large and varietyof molecular structures exist in their molecules.The field has become morecomplex on the phenomenon of the isomerism.They are two main systems ofnomenclature of organic compounds.They are
1.Trvial system2.IUPAC system
Trivial System:
In this system whenever a new compoundis discovered it is given an individual name.These names are called Trivialnames.These names are also called Common names.
Examples:
(a) Acetic acid derives its name from vinegar of which it is chiefconstituent.(b) Formic acid was named as it was obtained from red ants.(c)The name oxalic acid, malic acid and citric acid is derived frombotanical sources.(d)Urea and Uric acid have been derived from animal sources.(e)The liqiud that is obtained by the destructive dstaillation of woodwas named as wood spirit.Later on it was called methyl alcohol.(f)Methane is called as marsh gas because it is produced in marshes.
IUPAC System:
IUPAC nomenclature of organic chemistry is asystematic method of naming organic chemical compounds as recommended bythe "International Union of Pure and Applied Chemistry (IUPAC)". Ideally, everypossible organic compound should have a name from which an unambiguousstructural formula can be drawn.The name assigned to an organic compound onthe basis of latest IUPAC rules is known as systematic name.
Features Of IUPAC System:
(a) A given compound can be assigned only one name(b) This system is helpfull in naming the complex organic compounds(c) This system is helpful in naming the multifunctional groups.(d) This is a simple,systematic and scientific method for the nomenclature oforganic compounds.
Now let us confine our discussion to nameorganic molecules in IUPAC system. In English we have 26 alphabets so let usgive name and molecular formulae to that 26 alphabets as shown. For this weneed to know the basic rules for naming organic molecules.
Structure of the methanemolecule: the simplesthydrocarbon compound.
So now let us study some basic rules for organic chemistry.

So now let us know how IUPAC names are given for Alphabets
1.
If we consider above example we can observe that themolecule that is present is cyclo propane.At 1,2 positions we find two methylsubstitutions.As a result the name of the above compound is 1,2-dimethylcyclopropane If we count the number of carbons we get 5 carbons and simillarly we get10hydrogens, Hence the molecular formula of this compound A is

If we consider the above compound it is a bicyclo compound and itsaturated.As a result the name of the compound bicyclo[2.2.0]hexaneIt contains 6 carbons and 10 hydrogens as a result the molecular formula of thecompound is

This is how we can give names and molecular formulae for alphabets by using IUPACnomenclature. Let us now generate the molecular formula of a name.

Alphabet IUPAC Name Molecular Formula
Total : C35H84
Total : C52H124
C87H208
So in above example the number of Carbons and Hydrogens are added in word "Chemical" and theirtotal is witten simillarly write the total for engineering as follows shown in above example.
Now add the two toatals we get the molecular formula of "Chemical Engineering"
This can be done as follows:
1.Chemical
2.Engineering
C35H84
C52H124
Chemical Engineering C87H208
So this is how one can generate molecular formulae for any name. Thereforemolecular name for a person can also be generated on same lines.
So Hurry Up try to generate molecular formulae for ur name....................
