WebThere appear to be two different types of strain that can be developed by the formation of a new phase in a matrix phase. The first type of strain occurs only when both phases are crystalline and is that caused by a misfit, due to different lattice parameters — eq. (15), between two coherent phases. WebEvery organic molecule generally exist in different structural isomers / conformation. The relative study of stability between different conformation is referred as conformational analysis. Every conformational analysis is based on magnitude of strain / discomfort associated with the structural isomer for the given organic molecule. eighth\\u0027s hj fomc voting 2022

"In chemistry, a molecule experiences strain when its chemical structure undergoes some stress which raises its internal energy in comparison to a strain-free reference compound. The internal energy of a molecule consists of all the energy stored within it. A strained molecule has an additional amount of internal energy which an unstrained molecule does not. This extra internal energy, or strain energy, can be likened to a compressed spring. Much like a compressed spring must be held in … " - Different types of strain organic chemistry
