WebFeb 20, 2024 · Nuclear Isomer Definition. Nuclear isomers are atoms with the same mass number and atomic number, but with different states of excitation in the atomic nucleus. The higher or more excited state is called a metastable state, while the stable, unexcited state is called the ground state. WebGeometric (cis/trans) isomers. With a molecule such as 2-butene, a different type of isomerism called geometric isomerism can be observed. Geometric isomers are isomers in which the order of atom bonding is the same but the arrangement of atoms in space is different.The double bond in an alkene is not free to rotate because of the nature of the …

WebMaleic acid is the cis isomer and fumaric acid is the trans isomer. Elaidic acid and oleic acid are cis-trans isomers. The former is solid at room temperature (melting point = 43 o C) and the latter is found to be liquid, with a melting point of 13.4 o. Thus, it can be noted that trans isomers generally have higher melting points than their cis ... WebStereochemistry focuses on stereoisomers. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. [1] [2] This contrasts with structural isomers ...
