Open chain compound: Open chain compounds are those in which the end carbon are not joined with each other in this way they form a long chain of carbon atomH3C -CH2 -CH2 -CH3
There are four typeschemical formula of organic compound
1: Molecular formula
2: Condensed formula
3: Dot-cross formula
4: Structural formula
There are four mains reasons of existence of large number
1: Catenation
2: Isomerism
3: Strength of covalent bond
4: Multiple bonding
Organic chemistry are hydrocarbon and their derivatives in which covalently bonded carbon is an essential constituent.
CNG stands for compressed natural gas.
The general formula of Alkane is CnH2n+2
It is a mixture of hydrogen, methane and carbon monoxide.
Organic chemistry is the branch of chemistry which we study about macromolecules in living organisms like carbohydrates, proteins, lipids etc.
An atom or group of atoms or presence of double or triple bond which determines the characteristic properties of an organic compound known as functional group.
The compounds are said to be isomers if they have the same molecular formula by different arrangement of atoms in their molecules or different structural formula and phenomenon is called isomerism.
Coke is 98% carbon. It is left behind as residue of coal. It is mainly used as a reducing agent in the extraction of metals especially iron. It is also used as fuel
An atom or group of atoms or presence of double or triple bond which determines the characteristic properties of an organic compound known as functional group.
The gases which are found in coal gas are hydrogen, methane, carbon monoxide.
Organic compounds consisting of RCOOR functional group are called esters. The general formula of ether is R-C-OR R and R are alkyl gropes. They may be same or different such as.
The formula which represent s the actual number of atoms in one molecule of organic compound is called molecular formula. Example: Butane.
Our existence owe to organic compounds because these compounds are part of everything from food we eat to the various items we use in daily life to fulfill our needs.
Coke is 98% carbon. It is left behind as residue of coal.It is mainly used as a reducing agent in the extraction of metals especially iron. It is also used as fuel.
Organic compounds have low melting or boiling points due to presence of covalent bond which is weaker than ionic bond.
Organic chemistry is the branch of chemistry in which we study about macromolecules in living organisms lime carbohydrates, proteins, lipids etc.
A large number of organic compounds are used as medicines by us. Most life saving medicines are synthesized in laboratories.
It is a solution of ammonia gas in water. It is used to prepare nitrogenous fertilizer.
Carbon gets minimum energy and maximum stability by sharing its four valence electrons with other atoms. In this way it completes its octet.
Organic chemistry are hydrocarbon and their derivatives in which covalently bonded carbon is an essential constituent.
Alkyl radicals are derivatives of alkanes. They are formed by the removal of one of the hydrogen atom of an alkane and are represented by a letter ‘R’. Their names is written by replacing ‘ane’ of alkane with ‘yl’.
An atom or group of atoms or presence of double or triple bond which determines the characteristic properties of an organic compound is known as the functional group. Example-OH group is the functional group of alcohols, which fives charactristics properties of alcohols.
It is a mixture of hydrogen, methane and carbon monoxide.
This is because intermolecular forces between the molecules are weak
Natural gas is used as fuel in homes as well as fuel in homes as well as in industries. It is used as fuel in automobiles as compressed natural gas (CNG). Natural gas is also used to make carbon black and fertilizer.
Heterocyclic compounds that contain one or more atoms other than that of carbon atoms in their rings are called heterocyclic compounds.
