Question

In dehydrohalogenation reaction, hydrogen and halogen are removed from:

• A. the same carbon atom
• B. the adjacent carbon atoms
• C. the isolated carbon atoms
• D. any two carbon atoms

Answer 1

The correct option is B the adjacent carbon atoms

The dehydrohalogenation reaction takes place as follows:

$R-C{H}_2-CH\left(X\right)-R\to R-CH=CH-R+HX$

In this process, hydrogen and halogen are removed from adjacent carbon atoms.

Option B is correct.
