- Show the steps necessary to transform the acid on the left into the compound on the right. Be sure to use SOCl2Answer each part ASAP with proper explanation within 10 MINUTES. If you can't answer within 10 minutes then don't answer, otherwise I will give you dislike and tag it under incorrect solution !!Checking my answer, there was difference with solution. (organic chemistry smith 5th ed 2.47P (d)) Solution said 'the acid base reaction between pentyne and ammonia is product way because pka of pentyne is 25, ammonia is 38 so pentyne will be deprotanted by ammonia.' but I think (and as written in the book) NH4+ is stronger acid than pentyne and acid-base reaction works when reactant is stronger acid than product conjugate acid. It isn't match that pentyne makes NH4+. who is incorrect?
