$(I)$ As wavelength decreases, the lines in the series converge
$(II)$ The integer $n_{1}$ is equal to $2$
$(III)$ The lines of longest wavelength corresponds to $\mathrm{n}_{2}=3$
$(IV)$ The ionization energy of hydrogen can be calculated from wave number of these lines
They were labelled $ A$ and $B$ for testing.
$A$ and $ B $ were separately taken in test tubes and boiled with $NaOH$ solution.
The end solution in each tube was made acidic with dilute $HN{O_3}$ and then some $AgN{O_3}$ solution was added.
Substance $B$ give a yellow precipitate.
Which one of the following statements is true for this experiment
Which conformer of above compound is most stable across $C_2 - C_3$ ?
