There's a Multiple Choice question in my Text book

In its Nucleophilic substitution reaction , aryl halide resembles

a) Vinyl Chloride
b) allyl chloride
c) Benzyl Chloride
d) ethyl chloride

The answer given is a) Vinyl chloride

I want to ask is Since aryl halide is an aromatic compound how can the Answer be Vinyl Chloride ?

They are asking for the ease of nucleophilic substitution, nucleophilic substitution in aryl halides and vinyl halides requires special conditions and does not occur under "normal" conditions.

Sry But i didnot understand .
Can you please Explain it to me once again

What do you not understand?
You know what nucleophilic substitution is I assume?

[Nitin_Naudiyal]

I know that nucleophilic substitution reaction means that a nucleophile
attacking an electrophile

but i didnot understand the question

In its Nucleophilic substitution reaction , aryl halide resembles

What do they exactly want to ask ?
resembles in the sense what ?
Reaction mechanism
Structure
Compound
Functional group

They are talking about structure. In vinyl and aryl halides you have an electron rich pi electron cloud which can be seen a clouds of negative charge about the C-C bonds. A nucleophile cannot approach this as a nucleophile has a negative charge, like repels like. So in vinyl and aryl halides the nuleophilic reaction cannot occur unless very special conditions are used.
