Question

Ethylene dichloride and ethylidene chloride are isomeric compounds. The false statement about these isomers is that they

A. are both hydrolysed to the same product  
B. contain the same percentage of chlorine
C. are position isomers
D. react with alcoholic potash and give the same product
Answer :   are both hydrolysed to the same product
Solution :
On hydrolysis both gives different compounds.
\[\underset{\text{Ethylene dichlorid}e}{\mathop{C{{H}_{2}}Cl-C{{H}_{2}}Cl}}\,\xrightarrow{aq.\,KOH}\]       \[\underset{\text{Glycol}}{\mathop{C{{H}_{2}}OH-C{{H}_{2}}OH}}\,\]
