Interpretation Introduction
Interpretation:
The pKa of HCN is given. Its Ka is to be calculated.
Concept introduction:
pKa is defined as negative common logarithm of the Ka values.
pKa=-logKa
By substituting the pKa value in this equation the value of Ka can be calculated.
To calculate:
The Ka value of HCN from its pKa value.

I asked this already, and the person explained why those are the correct products, as opposed to what we would think should be the correct products. That's the opposite of what the question was asking. Why are they not the correct products? A reaction mechanism for how we arrive at the correct products is requested ("using key intermediates").
