JEE Main 2025 — 2 April, Morning Shift — Question 15

According to Bohr's model of hydrogen atom, which of the following statement is incorrect?

Option A:
Radius of $4^{\text {th }}$ orbit is four times larger than that of $2^{\text {nd }}$ orbit
Option B:
Radius of $6^{\text {th }}$ orbit is three times larger than that of $4^{\text {th }}$ orbit
Correct
Option C:
Radius of $8^{\text {th }}$ orbit is four times larger than that of $4^{\text {th }}$ orbit
Option D:
Radius of $3^{\text {rd }}$ orbit is nine times larger than that of $1^{\text {st }}$ orbit

Answer: B

$r \propto n^{2}$

$r_{6}=\frac{36}{16} r_{4}$

$r_{6}=\frac{9}{4} r_{4}$

Option (2) is incorrect
