The two structural isomers of the given alkane C 8 H 18 has to be drawn which has longest chain of five carbon atoms (one ethyl side chain and one methyl side chain). Their systematic name has to be given Concept introduction: IUPAC naming for Alkane: Name the main chain: Find the longest carbon chain and name the chain according to the number of carbon atoms it contains; is also the suffix part of the name. Number the carbon atoms in the main chain: The carbons are numbered, in which the substituents must get lowest possible numbers. Identify the substituents, and number each: The number at where substituents are present has to be noted. The substituents written as prefix. Write the names as a single word: Use the hyphen to separate the numbers from the different prefix; commas to separate numbers. If two or more different substituents are present, arrange them in alphabetical order. If two or more identical substituents are present, use prefixes di-, tri-, tetra-, but this particular prefix should not be used for alphabetizing purpose. Isomers: Isomers are the compounds which have same molecular formula but have different properties. There are different types of isomers known for example, structural isomers, stereoisomers, geometrical isomers and optical isomers etc Stereoisomerism: The compounds which have same molecular formula but there is difference in the spatial arrangements of atoms are known as stereoisomers and this phenomenon is known as stereoisomerism.

Interpretation Introduction

Interpretation: The two structural isomers of the given alkane C8H18 has to be drawn which has longest chain of five carbon atoms (one ethyl side chain and one methyl side chain). Their systematic name has to be given

Concept introduction:

IUPAC naming for Alkane:

Name the main chain: Find the longest carbon chain and name the chain according to the number of carbon atoms it contains; is also the suffix part of the name.

Number the carbon atoms in the main chain: The carbons are numbered, in which the substituents must get lowest possible numbers.

Identify the substituents, and number each: The number at where substituents are present has to be noted. The substituents written as prefix.

Write the names as a single word: Use the hyphen to separate the numbers from the different prefix; commas to separate numbers. If two or more different substituents are present, arrange them in alphabetical order. If two or more identical substituents are present, use prefixes di-, tri-, tetra-, but this particular prefix should not be used for alphabetizing purpose.

Isomers: Isomers are the compounds which have same molecular formula but have different properties. There are different types of isomers known for example, structural isomers, stereoisomers, geometrical isomers and optical isomers etc

Stereoisomerism: The compounds which have same molecular formula but there is difference in the spatial arrangements of atoms are known as stereoisomers and this phenomenon is known as stereoisomerism.

Name all unbranched ether and alcohol isomers with formula C5H12O, and write their structural formulas.

Glucose, C6H12O6, contains an aldehyde group but exist predominantly in the form of the cyclic hemiacetal show below. A cyclic hemiacetal is formed when the —OH group of one carbon bonds to the carbonyl group of another carbon. Identify which carbon provides the —OH group and which provides the —CHO? Give a functional isomer of glucose and draw its structure.

write the structure formulas of alkanes with molecular formula C6H14, which with chlorine give: a) three monochlorinated isomers? b) five monochlorinated isomers c) only two monochlorinated isomers
