Determine atomic/molecular structure of organic compounds using nuclear magnetic resonance spectral data

Determine the number of equivalent H atoms in 2,2,4-trimethylpentane and the number of H atoms in each set:

2,2,4-trimethylpentane has four sets of equivalent H atoms:

The 3 equivalent methyl groups give 9 equivalent (H^a) atoms

The methylene group gives 2 equivalent (H^b) atoms

The methine group gives one (H^c) atom

The 2 equivalent methyl groups give 6 equivalent (H^d) atoms:
