Question

Geometrical isomers are differ in:

• A. poisition of functional group
• B. position of atoms
• C. spatial arrangement of atoms
• D. length of carbon chain

Answer 1

Answer: (C)

spatial arrangement of atoms


Geometrical isomers also called as cis-trans isomers or EZ isomers are the isomers which differ from one another in their geometry or spatial arrangement of atoms. The two most common sources of geometric isomers are double bonds and ring structures.
There is a free rotation in C-C single bond, whereas restricted rotation about the double bond means that the relative positions of the substituent groups above and below the double bond are significant.
