Hybridization predicts the geometry and bond angles in complex molecules and it helps in the understanding of how four equivalent bonds in methane (CH? )  can be formed from atoms like carbon. For observed molecular geometries, it explains the formation of the equivalent orbitals (like sp³, sp², sp).

In molecular shape prediction, VSEPR (Valence Shell Electron Pair Repulsion) theory is important because based on the repulsions between the electron pairs around the central atom, it helps in predicting the three-dimensional shape of molecules. The 3D shape influences the molecule's chemical and physical properties including reactivity, polarity, and intermolecular forces.

You will get medical college according to you marks and college cutoff. You should make a list of colleges according to your marks. Then participate in counselling for admission process. 

The NCERT Exemplar questions go beyond the textbook questions as they are designed to be more challenging and conceptually advanced. Practicing the NCERT exemplar provides a better understanding of complex topics like conductance and electrochemical cells. It also helps in better preparation for the entrance exams. The exemplar often involves multi-concept, application-based, and analytical problems.

A salt bridge in a galvanic cell maintains electrical neutrality by allowing the ions to flow between the two half-cells. It ensures the continuous flow without participating in the reaction. The salt bridge prevents the charges accumulation as such an accumulation can halt the electrochemical reaction by stopping the flow of electrons.

The Nernst equation in Electrochemistry is important because, under non-standard conditions, it allows us to calculate the electrode potential of the half and full cell. This equation shows how the potential of the cell varies with the temperature, concentration, and pressure. In electrochemical cells, it helps in predicting the spontaneity and direction of redox reactions.
