Q

What is structural isomerism?

A

Mol which have the same molecular formula but a different structural formula

17
Q

What is chain isomerism?

A

Same molecular form but a diff arrangement of the atoms in the C chain

18
Q

What is positional isomerism?

A

Mol have the same funct group but it is in a dif pos in the mol

19
Q

What is funct group isomerism?

A

Mol have the same mol formula but have dif funct groups

20
Q

What is geometric isomerism?

A

Mol which have the same str formula but dif arrangement of atoms due to the pres of 1/more C=C bonds

21
Q

Z isomerism

A

Same side

22
Q

E isomerism

A

opposite sides

23
Q

Which E or Z is given a higher priority?

A

Higher atomic number given high priority

24
Q

What are the req for geometric isomerism?

A

Restricted rotation due to C=C double bond
Two different groups of the LHS and two different groups on the RHS

25
Q

In trans bonding in terms of pos and priority in double bond where is E?

A

Highest priority groups are on opposite sides of the double bond

26
Q

In cis bonding in terms of pos and priority in double bond where is Z?

A

Highest priority groups are on the same side of the double bond

27
Q
