JEE Main2016ChemistryHaloalkanes and HaloarenesActual
Which one of the following reagents is not suitable for the elimination reaction?
Options
- AN a I
- BN a O E t / E t O H
- CN a O H / H 2 O ,   ∆
- DN a O H / H 2 O - E t O H
Correct answer
A. N a I
Step-by-step solution
To get the desired product, an elimination reaction needs to occur. For an elimination reaction, a strong base ( O − Et,       O − H ) needed. Because I − is not basic, NaI is not suitable for the following reaction. With N a I, substitution takes place.
