Why phenol can also be prepared from chlorobenzene(Dow''s process)
Time taken for an electron to complete one revolution in the Bohr orbit of hydrogen atom is: (1) 4 Π mr 2 / nh (2) nh/ 4Π 2 mr (3) nh/ 4Π 2 mr 2
The uncertainty in momentum of an electron is 1 x10 -5 kg- m/s . The uncertainty in its position will be (h= 6.62 x 10 -34 kg - m 2 / s): (1) 1.05 x 10- 28 m
