Vedclass · Answer

(C) The Assertion is based on Heisenberg's Uncertainty Principle,which states that it is impossible to determine simultaneously the exact position and exact momentum of a microscopic particle like an electron. This is a fundamental law of quantum mechanics. The Reason states that the path of an electron in an atom is clearly defined. This is incorrect because,according to quantum mechanics,electrons do not move in well-defined circular orbits (as proposed in the Bohr model). Instead,they exist in orbitals,which are regions of space where the probability of finding an electron is high. Therefore,the path of an electron cannot be defined.

Assertion : It is impossible to determine the exact position and exact momentum of an electron simultaneously.
Reason : The path of an electron in an atom is clearly defined.
