WebParamagnetic substances are those substances that get weakly magnetized in the presence of an external magnetic field. In the presence of an external magnetic field, these substances tend to move from a region of a weak to a strong magnetic field. In other terms, we can say that these substances tend to get weakly attracted to a permanent magnet. http://dictionary.sensagent.com/para%20chemistry/en-en/ hulagu han ertugrul

WebFeb 21, 2013 · When to use italics for "para" etc. Jump to solution I know that italics are required when ortho, meta, and para are included as part of a chemical name (e.g. para -methoxyphenol). However, I'm confused as to whether or not they should be in italics when used outside of chemical names. WebIn addition, the para product would be expected to be preferred over the ortho product, due to steric considerations. Electron-withdrawing substituents on an aromatic ring are ring-deactivating, making it harder for further substitution reactions to occur. These are mostly carbonyl-containing groups, as well as alkyl halides.
