In this question, we have ethine, the p -k -a value of 25 and water having a p -qa value of 15 .7 and ammonia, n -h -3, having a p -k -a value of 36.
00:29
We're going to write the direction which favors equilibrium of acid -based reaction of ethyne.
00:39
So that here, acid -based reaction.
00:43
We are getting this acid -based reaction question.
00:48
With the equilibrium will be shifting into the side having the largest pk.
00:57
This for part a, the acid -based reaction of epine with oh -minus.
01:06
That is h c triple bone c h minus plus or h minus charge will be coming into the edge and this will be h c triple c minus plus h2 having a pk value 15 .7.
01:28
That is this is the left side and this is the right side.
01:33
Shifting here the pk value is 25...
