The McNemar test is a test on a 2x2 classification table when you want to test the difference between paired proportions. Chi-square test for 2X2 tables compares the tallies or counts of categorical responses between two (or more) independent group

A discordant pair is a matched pair in which the outcomes differ from the members of the pair whereas concordant pair is a matched pair in which the outcome is same for each member of the pair.
