QJEEM03Chc541: JEE Main 2003 Chemistry - Class 11 JEEM03Chc541 Solution: In Bohr series of lines of hydrogen spectrum, the third line…

In Bohr series of lines of hydrogen spectrum :- Red end means end of visible region which is balmer series of lines so n will be 2

Now for third lines with respect to Balmer series means n = (2 + 3) = 5^th line

$$\therefore$$ n₁ = 2 and n₂ = 5

For 2 $$\to$$ 5 electron will need energy to jump as 2 > 5 so no spectrum will release instead energy will be absorbed.

$$\therefore$$ 5 $$\to$$ 2
