Answer 8

1. Chain Isomers
2. Positional Isomers
3. Functional Group Isomers

Question 9

what are chain isomers ?

Answer 9

• These type of isomers tend to have similar chemical properties and slightly different physical properties
• These isomers arise due to different arrangements of the carbon skeleton in the molecules.

Question 10

what are positionla isomers ?

Answer 10

• These isomers have same carbon skeleton and same functional group, but the functional group is in a diffrent postion
• The isomers tend to have similar chemicla properties and slightly diffrent physical properties

Question 10

what are positionla isomers ?

Answer 10

• These isomers have same carbon skeleton and same functional group, but the functional group is in a diffrent postion
• The isomers tend to have similar chemicla properties and slightly diffrent physical properties

Question 11

what are functionla group isomers ?

Answer 11

• The isomaers have the same molecular formula and carbon skeleton, but different functional groups
• This type of isomers tend to have different chemical properties and different physical properties

Question 11

what are functionla group isomers ?

Answer 11

• The isomaers have the same molecular formula and carbon skeleton, but different functional groups
• This type of isomers tend to have different chemical properties and different physical properties

Question 12
