Difference between σ and π bonds σ bond π bond (i) The orbitals overlap along their axes. (ii) The overlap is quite appreciable and the bond formed is a strong bond. (iii) s-orbitals can participate in the bond formation. (iv) In case of p-orbitals, the participating lobe is stretched and the size of the other
Chemical bond: The attractive force which holds together the constituent atoms of chemical compounds is called chemical bond. Combination of atoms: It. is universal law of nature that systems with lower energy are more stable. So atoms combine to form a molecule because it has a· lower energy i.e., more stable. Modern concept of chemical
According to Newton’s corpuscular theory, light is propagated as a stream of particles, called corpuscules. This could justify the phenomenon of reflection and refraction of light but failed to explain the phenomenon of diffraction, interference etc. Clerk Maxwell suggested that light waves are associated with both electric and magnetic fields i.e., light may be described
