Which among the following is a heaviest isotope of water?
- A \(\mathrm{T}_{2}{ }^{17} \mathrm{O}\)
- B \(\mathrm{T}_{2}{ }^{16} \mathrm{O}\)
- C \(\mathrm{HD}^{18} \mathrm{O}\)
- D \(\mathrm{T}_{2}{ }^{18} \mathrm{O}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{T}_{2}{ }^{18} \mathrm{O}\)
Step-by-step Solution
Detailed explanation
Isotopes of water are \(=\mathrm{H}_{2} \mathrm{O}, \mathrm{D}_{2} \mathrm{O}, \mathrm{H}_{2} \mathrm{O}^{17} \ldots\) etc.
Mol.wt
(A) \(\mathrm{T}_{2} 0^{17} \rightarrow\) 23
(B) \(T_{2}{ }^{16} \mathrm{O}\rightarrow\) 22
(c) \(\mathrm{HD}_{0}^{18}\rightarrow\) 21
(D) \(T_{2}{ }^{18} 0\rightarrow\) 24
Heaviest \(=T_{2}^{18} 0\)
