Number of Chemical Shift Non-Equivalent Protons in α-pinene
Alpha-pinene is a bicyclic monoterpene commonly found in pine trees. It has a complex structure that results in multiple chemical shift non-equivalent protons on its H NMR spectrum.
Explanation:
- The alpha-pinene molecule contains a total of 10 non-equivalent protons due to its structural complexity.
- These protons are distributed across various chemical environments within the molecule, leading to distinct chemical shifts in the NMR spectrum.
- The protons in alpha-pinene are located in different positions such as allylic, vinylic, and methyl groups, each contributing to the total number of non-equivalent protons.
- The presence of double bonds and cyclohexane rings in the molecule further increases the number of non-equivalent protons.
Therefore, the correct answer is (d) 10, as alpha-pinene is expected to exhibit 10 chemical shift non-equivalent protons in its H NMR spectrum.
