Question

Please outline the mechanism of this reaction:

Step 1: carbon and calcium oxide
Step 2: addition of water to the product from step 1
Step 3: addition of excess NaNH2, followed by CH3I

The product is 2-butyne.

Thank you

Answer 1

Your starting product?

Answer 2

You're missing something.

Answer 3

Sorry, I was AFK. Seems like the starting material is C and CaO.

The complete question is:
What would be the MAJOR product(s) of the following sequence of reactions?
Step 1: carbon and calcium oxide
Step 2: addition of water to the product from step 1
Step 3: addition of excess NaNH2, followed by CH3I
A) methylamine
B) 2-iodobutane
C) 2-iodobutene
D) 2-butyne (Correct)
E) 1,2-diiodoacetylene

It's possible it's a mistake...

Answer 4

I think I found a good lead:

CaO + 3 C → CaC2 + CO
