Q

What is isomerism?

A

Isomerism are phenomenon of two or more compound which as the same molecular formulae but different structures or arrangement

18
Q

How many tyoes of isomers do we have ?

A

2

19
Q

The types of isomers are ?

A

Structural and stereo isomerism

20
Q

What is skeletal isomerism

A

This is the type of isomerism that are re arranged to create different structure

21
Q

Positional isomerism

A

This isomer differs only in the position occupied by a particular atom in the carbon atom

22
Q

What is functional isomerism ?

A

This isomerism involve compound with different functional groups

23
Q

What is metamerism

A

Is an isomer brought about the unequal distribution of carbon atom on either side of a functional group

24
Q

What is stereo isomer

A

These are organic compounds having the same molecular formulae and sequences of bonded atoms but differ in their spiritual arrangement of atom

25
Q

What is substitutional reaction

A

A substitutional reaction is the direct displacement of an atom or group by another atom or group
