Remedy: sigma-bond is more powerful. It is because sigma-bond is formed by head-on overlapping of atomic orbitals and Π bond is fashioned by side wise overlapping.
Dilemma eighteen. From bonding and antibonding molecular orbitals, which one particular has reduce Power and which one has increased balance?
II. Light ray suffers refraction at the point of incidence and at The purpose of emergence whilst passing throughout the prism.
Dilemma 1. Go over the main attributes of extensive method of the periodic desk. Exactly what are the advantages of lengthy . sort of periodic desk?
Clarification: Proton and electron have equivalent but opposite rates. Proton have beneficial and electron have negative demand. Demand on an alpha particle is equal to that of two protons.
