Question:

The final major product of the following reaction is :


Correct Option:

Solution:

A proton and a $\mathrm{Li}^{3+}$ nucleus are accelerated by the same potential. If $\lambda_{\mathrm{Li}}$ and $\lambda_{\mathrm{p}}$ denote the de Broglie wavelengths of $\mathrm{Li}^{3+}$ and proton respectively, then the value of $\frac{\lambda_{\mathrm{Li}}}{\lambda_{\mathrm{p}}}$ is ____________ $x \times 10^{-1}$. The value of $x$ is [Rounded off to the nearest integer] [Mass of $\mathrm{Li}^{3+}=8.3$ mass of proton]
