Naming of Organic Compounds containing multiple bonds 

Organic Compounds containing multiple bonds

1. Select longest continuous chain of c-atom containing multiple bonds. 2. If only one multiple bonds is present (either double or triple) then C-atom form where multiple bond begins, gets lowest position number. 3. If one type of multiple bond present more than one time, numbering should be done in a way such that the […]

IUPAC name format 

Larger number of side chain rule

IUPAC name format Cyclic Compound: S. prefix + P. prefix + word root + P. suffix + S. suffix Acyclic Compound: Prefix + word root + P. suffix + S. suffix  Rules 1. Rules for selection of Carbon chain (parent chain) Longest chain rule:  select longest continuous chain of carbon atom Larger number of side […]



Prefix is another part of name which appears before word root. There are two types of prefix: Primary prefix Secondary prefix   Primary Prefix: It is used to indicate/represent alicyclic (cylic aliphatic) compounds. For this, word “cyclo” is added before word root. Example: cyclo + prop + ane = cyclo propane cyclo butane   Secondary […]



Suffixes It is another part of name that comes after the word root. There are two types of suffixes: Primary Suffix Secondary Suffix   Primary Suffix: It is used to indicate whether the parent chain is saturated or unsaturated.   Note: If primary suffix begins with consonant like di, tri, tetra, etc. then extra “a” […]

Word Root 

It is the basic unit of name and represents the number of carbon atoms present in the parent chain. Parent Chain It is the longest continuous chain of carbon atom containing functional group (or, and) multiple bonds (if present). Number of carbon atoms in the parent chain Word root 1 Meth 2 Eth 3 Prop […]

Nomenclature of Organic Compounds Introduction 

Types of Naming System: Common or Trivial System IUPAC (International Union of Pure and Applied Chemistry) System Common System This system names the organic compounds on the basis of their source of origin. IUPAC System This system names the organic compounds on the basis of their structure. According to the IUPAC system, the name of […]

Determinants of demand 

Price:  Demand is inversely related to price. If price increases, demand decreases and vice versa. But in case of Giffen goods (goods that are inferior and basic like low quality rice and bread for Nepalese), demand is directly related to price.  Price of complementary goods: Demand is inversely related to price of complementary goods. The […]

Types of Demand 

price demand

Price demand: Demand primarily dependent upon price is called price demand. This demand is sensitive or responsive to the change in price. In case of normal goods, demand increases with fall in price and vice versa. But in case of giffen goods demand increases even there is rise in price. Cross demand: Demand primarily dependent […]

Law of Demand 

The law of demand states that the demand is inversely related to price other things remaining constant (ceteris paribus). It means if price raises demand contracts or decreases and if price diminishes demand expands or increases. The law of demand operates only if factors determining demand other than prices are constant. It means prices of […]

Meaning of Demand 

Meaning of demand –          Desire backed up by ability and willingness to pay –          Quantity of a commodity that a consumer want to purchase at a certain price during a certain time period   Mere desire is not sufficient for demand. The consumer must have ability to pay and willingness to pay for fulfillment of […]
