The intermolecular bonds are the bonds between different compounds. Now, here we have two alkanes. We have neopentane and pentane. The intramlecular bonds within neopentane are the carbon carbon Covalent bonds and carbon H Covalent bonds. Likewise, the intramolecular bonds in pentane are the carbon carbon Covalent bonds and the carbon H Covalent bonds, which aren't shown. So for both types of alkanes and in fact, for all alkanes, the intramlecular bonds are Covalent bonds.
