WebThe important postulates of Werner’s theory are: The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and secondary valency. The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number. The number of secondary valences is fixed for ... http://definecoordinationnumberofsolidshaalaa.com/

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 ...

A coordinate covalent bond is a covalent bond in which one atom (i.e., the donor atom) supplies both electrons. This type of bonding is different from a normal covalent bond in which each atom supplies one electron. marginal spur formation
