Which of the following represents the systematic name of the compound `CH_(2)=CH-CH_(2)Cl` ?

Options

A. (1) Allyl chloride
B. (2) `3`-Chloroprop-`1`-ene
C. (3) `1`-chloroprop-`3`-ene
D. (4) Vinyl chloride

Answer

B

Explanation

The principal function is the `C=C` bond. Thus, it should be named as a derivation of an alkene. The numbering should start from the end closer to the `C=C` bond :
`overset(1)(CH_(2))underset(3-"chloroprop-1-ene")(= overset(2)(CH)-overset(3)(CH_(2))Cl)`
The common name of the compound is allyl chloride.
