Dehydrohalogenation is an elimination reaction that eliminates a hydrogen halide from a substrate. The reaction is usually associated with the synthesis of alkenes.Here option C is correct bcoz Neopentyl don't have alpha H so dehydrohalogenation doesn't occurs.

Which one of the following organohalogen compounds when heated with al...
Neopentyl chloride, also known as 2,2-dimethylpropane chloride, does not undergo dehydrohalogenation reaction when heated with alcoholic potassium hydroxide.
Explanation:
Dehydrohalogenation is a reaction in which a halogen atom (commonly chlorine, bromine, or iodine) is eliminated from an organic molecule. This reaction is typically carried out by heating the organic compound with a strong base, such as alcoholic potassium hydroxide (KOH).
In order for dehydrohalogenation to occur, the organic compound must have a hydrogen atom attached to the carbon atom bearing the halogen. This hydrogen atom is then abstracted by the base, leading to the formation of an alkene.
Let's analyze the given options:
a) Secondary butyl chloride:
Secondary butyl chloride has a hydrogen atom attached to the carbon atom bearing the chlorine atom. Therefore, it can undergo dehydrohalogenation and form an alkene.
b) Isopropyl chloride:
Isopropyl chloride also has a hydrogen atom attached to the carbon atom bearing the chlorine atom. It can undergo dehydrohalogenation and form an alkene.
c) Neopentyl chloride:
Neopentyl chloride does not have a hydrogen atom attached to the carbon atom bearing the chlorine atom. Therefore, it cannot undergo dehydrohalogenation. The carbon atom bearing the chlorine is bonded to three methyl groups and there is no available hydrogen for elimination.
d) Isobutyl chloride:
Isobutyl chloride has a hydrogen atom attached to the carbon atom bearing the chlorine atom. It can undergo dehydrohalogenation and form an alkene.
Based on the analysis, the correct answer is option 'C' - Neopentyl chloride.
