And let's compare to the acidity of alkanes. So, as an example, let's use the simplest alkyne acetylene, and let's use the simplest alkane known as methane. So we basically want to determine which one of these two hydrocarbon compounds is a better Bronx Laric acid. Recall that a bronciid Laric acid is a compound that is capable of donating NH plus ion. So we want to figure out which one of these compounds is better at donating NH plus atom. So let's look at reaction one.
