MARKS App · Accepted Answer

There are nine primary hydrogens and one tertiary hydrogen in 2 -methyl propane. Tertiary hydrogen atoms react with Cl about 5.5 times as fast as primary. Even though the primary hydrogens are less reactive, there are so many of them that the primary product is the major product.
