Show Answer
Answer:
Correct Answer: D
Solution:
Addition - $ CH\equiv CH+3H_2\xrightarrow{Ni}CH_3-CH_3 $
Substitution - $ CH\equiv CH+Na\xrightarrow{{}}CH\equiv {C^{-}}N{a^{+}}+\frac{1}{2}H_2 $
Polymerization - $ 3CH\equiv CH\underset{Polymerization}{\mathop{\xrightarrow{hotCutube}}}\underset{Benzene}{\mathop{C_6H_6}} $
