What is a carbocation?
A carbon with a positive charge bonded to another carbon
Explain the relationship between the amount of carbons in a carbocation and stability?
More carbons in a carbocation means more stability so more relative abundance

Chemical test is cheaper and quicker IR does not destroy the compound
