FINAL ANSWER:
HNMR: 3 peaks
Carbon NMR: 5 peaks
Step-by-step explanation:
In 1,1-Dimethylcyclopentane, there are different types of hydrogen (proton) and carbon environments, which result in distinct peaks in the nuclear magnetic resonance (NMR) spectra.
For HNMR (Proton NMR), you would observe 3 peaks. This is because there are three different types of hydrogen atoms within the molecule: the hydrogen atoms on the methyl (CH3) groups (2 peaks), the hydrogen atoms on the methylene (-CH2-) group (1 peak), and the hydrogen atoms on the cyclopentane ring (all equivalent and giving 1 peak).
For carbon NMR, you would observe 5 peaks. This is because there are five distinct carbon environments within the molecule: the two carbon atoms in the methyl (CH3) groups (2 peaks), the carbon atom in the methylene (-CH2-) group (1 peak), and two different types of carbon atoms in the cyclopentane ring (2 peaks).
These unique chemical environments in 1,1-Dimethylcyclopentane lead to the observed number of peaks in both proton NMR and carbon NMR spectra.
