Which of the following reagents on reaction with acetylene yield same product?

Options

A. `(I), (II)`, and `(III)`
B. `(I), (II)`, and `(IV)`
C. `(II), (III)`, and `(IV)`
D. `(I), (III)`, and `(IV)`

Answer

`a`

Explanation

I.
II. `HC -= CH + overset(o-)(N)H_(2) rarr HC -= C^(o-) + NH_(3) ("Gas")`
III. `HC -= CH + overset(o-)(C)H_(3) rarr HC -= C^(o-) + CH_(4) ("Gas")`
IV. `HC -= CH + overset(o-)(O)H rarr HC -= C^(o-) + H_(2)O ("liquid")`
