Question

Nuclei having either the number of protons or neutrons as odd have ______ spin.

• A. \( \text{Integral spin} \)
• B. \( \text{Half integral spin} \)
• C. \( \text{Zero spin} \)
• D. \( \text{Positive spin} \)

Hint:

Nuclear spin is crucial in NMR spectroscopy, influencing signal strength and spectral resolution.

Answer 1

The Correct Option is B

Nuclear spin arises due to the quantum mechanical properties of nucleons (protons and neutrons). Nuclei with an odd number of protons or neutrons exhibit half-integral spin values, following quantum rules. In contrast, nuclei with even numbers of protons and neutrons generally have integral spin or zero spin.
