What was Bohr's theory Class 11?

In 1913, Neils Bohr proposed an atomic model that quantitatively explained the structure of hydrogen atom and its spectrum. It was based on the four postulates - Motion of electrons in an orbit, Fixed Energy of electrons, Transition of orbits by electrons, and Angular momentum of electrons.

What are common mistakes in chemistry notes?

Reversing the direction of one or more arrows during a chemical step is the most common mistake made by students when writing organic reaction mechanisms. Backwards arrow pushing usually derives from a student thinking about the movement of atoms, not the movement of electrons.

Can I directly start organic chemistry class 11?

Yes, you can start studying organic chemistry of 11th class after doing physical chemistry. Both branches of chemistry are interconnected and understanding the basics of physical chemistry can help you grasp some concepts in organic chemistry better.

What is the easiest chemistry to take?
