# What is the systematic name for an alkane that has 5 carbons and only primary hydrogens?

Do you mean $\text{neopentane}$, $C {\left(C {H}_{3}\right)}_{4}$?
Neopentane (you will have to supply the IUPAC name) only contains methyl hydrogens. How would the ""^13C{""^1H} and ""^1H $\text{NMR}$ spectra of this beast appear?
