Solution

ISOMERS:Compounds having same chemical formula are called as ISOMERS.

example: Consider C₄H_10.

They may be like CH(CH₃)₃ as well as CH₃-(CH₂)₂-CH_3.

_{IDENTICAL ISOMERS:Are also called as HOMOMERS, These are the isomers looking like they are representing two different forms that might lead to the conclusion that the two forms are different.}

GEOMETRICAL ISOMERS:These are isomers which are having same bonding connectivity but differ in configurations.

Example: CIS-TRANS,

E-Z, R-S, SYN-ANTI.

STRUCTURAL ISOMERS:These are the isomers having different bonding connectivity .

Example :Above given structures of C₄H₁₀ rrepresent. structural isomers.

Now from the given definitions of different isomers we can conclude that

1:GEOMETRICAL ISOMERS

The both given structures have same chemical formula they are isomers and are having same bonding connectivity but differ in their configurations they are so called GEOMETRICAL ISOMERS.

2:NONE

From the given structural details it can be said that both. have different chemical formulae, hence are not isomers.

3:IDENTICAL

since both have same molecular formulae and same bonding connectivity and are representing two different forms so are called IDENTICAL ISOMERS.

4:GEOMETRICAL ISOMERS

Since both are isomers and having same bonding connectivity but differ in configurations so are called GEOMETRICAL ISOMERS.
