1 Basic Principles of Organic Chemistry
Which of the following compounds will exhibit geometrical isomerism?
1) 1 - Phenyl - 2 - butene 2) 3 - Phenyl - 1- butene 3) 2 - Phenyl - 1- butene 4) 1, 1 - Diphenyl - 1 - propane
SOLUTION
We know that for Geometrical Isomer we need a double bond between carbon atom (this restricts rotation) and carbon atom at two sides must be linked to two different groups.
