QJEEM06Ch926a: JEE Main 2006 Chemistry - Class 11 JEEM06Ch926a Solution: According to Bohr's theory, the angular momentum of an electron …

According to Bohr's theory, the angular momentum of an electron in 5th orbit is

Multiple Choice Options

  • A 10 h/πh/\pi
  • B 2.5 h/πh/\pi
  • C 25 h/πh/\pi
  • D 1.0 h/πh/\pi

Step-by-Step Verified Solution

Formula of angular momentum of an electron,

mvr = nh2π{{nh} \over {2\pi }}

here n = 5

∴\therefore mvr = 5h2π{{5h} \over {2\pi }} = 2.5 hπ{{h} \over {\pi }}
