  6. Option F:

    HX2C=CH−C≡CH\ce{H2C=CH-C#CH}

  7. Option G:

    HX2C=C(CHX3)−CH=CHX2\ce{H2C=C(CH3)-CH=CH2}

  8. Option H:

    HX2C=CH−CH=CHX2\ce{H2C=CH-CH=CH2}

Answer: A

Step-by-step solution

Neoprene is produced by polymerization of 2-chloro-1,3-butadiene (chloroprene), which is structure 1: H₂C=C(Cl)CH=CH₂.
