Isomerism

Question 1

Types in structural isomerism.

Answer 1

1. Chain chain. Chain
   2.positional.
   3.Functional
   3.tautomerism
   4.Metamerism
   5.ring-chain isomerism

Question 2

Chain isomerism

Answer 2

It is due to the difference in arrangement of carbon atom constituting the chain.

Question 3

Position isomerism.

Answer 3

It is due to the difference in position occupied by the particular atom or group in The same Carbon chain All due to different positions of double or triple bonds in alkene or alkynes.

Question 4

Functional isomerism

Answer 4

Compounds having same molecular formula, but different functional groups in their molecule show functional isomerism.

Question 5

Functional isomerism

Answer 5

Compounds having same molecular formula, but different functional groups in their molecule show functional isomerism.

Question 6

tautomerism

Answer 6

It is a dynamic type of isomerism in which a substance behave as it has two different structures. Is known as tautomerism. The different forms are called tortomers. Tautomer are functional group isomers, which are inconvertible.

Question 7

What is the major difference Between tautomerism and resonance effect?

Answer 7

.1. In total marriage and atom changes place, but resonance involves a change of position of Π Electrons or unshared electrons
2. Totemers are different compounds, and they can be separated by suitable methods, but resonating structures cannot be separated, as they are imaginary structures of the same compound.
.3.

Question 8

Keto - Enol system

Answer 8

In this type of tautomer, one form contains the keto group(( >C=O), while the other contains the enolic(>C=C-OH) group.

Question 9

Why is Enol content more stable?

Answer 9

It is most stable because it has a conjugated. ( C=C-C=O) system and intramolecular H-Bonding

Question 10

Essential conditions for an aldehyde or a ketone to exhibit keto-Enol tautomerism

Answer 10

.1. It is essential that it Must have at least one Alpha hydrogen atom
.2. This tautomerism occurs both in acidic and basic medium.

Question 11

Metamerism

Answer 11

It is the isomerism in the Homologous Series. It is due to unequal distribution of carbon atoms on either side of the polyvalent functional group or atom. they are chain isomers with same functional groups.

Question 12

isomers which can be interconverted through rotation around single bonds are ?

Answer 12

conformers

Question 13

If two compounds have the same empirical formula, but different molecular formula, they must have.

Answer 13

Different molecular weight
