Q38 / 170 · Manipal (MET) 2020 · Chemistry
Which of the following notations shows the product incorrectly?
- A${ }_5^{10} \mathrm{~B}(\alpha, n){ }_7^{13} \mathrm{~N}$
- Correct answerB${ }_{96}^{242} \mathrm{Cm}(\alpha, 2 n){ }_{97}^{243} \mathrm{Bk}$
- C${ }_7^{14} \mathrm{~N}(n, p){ }_6^{14} \mathrm{C}$
- D${ }_{14}^{28} \mathrm{Si}(d, y){ }_{15}^{30} \mathrm{P}$
Solution
${ }_7^{13} \mathrm{~N} \xrightarrow{-{ }_2 \mathrm{He}^{+}}{ }_5^{10} \mathrm{~B}$
${ }_{96}^{242} \mathrm{Cm} \xrightarrow{-{ }_0 \mathrm{n}^1}{ }_{94}^{244} \mathrm{Pu}$
${ }_7^{14} \mathrm{~N} \xrightarrow{-{ }^{\mathrm{n}^1}}{ }_6^{14} \mathrm{C}$
${ }_{15}^{30} \mathrm{P} \xrightarrow[-\mathrm{g}]{-\mathrm{H}^1}{ }_{14}^{28} \mathrm{Si}$
Hence, the correct answer is option: 'B'.
