Tertiary alcohols are aliphatic alcohols in which the hydroxyl group (-OH) is attached to a tertiary carbon atom.
Thermionic emission is the boiling off of electrons from heated metals. It gives a source of electrons for cathode ray tubes.
Thermit welding is a group of welding processes in which fusion is produced by heating with superheated liquid metal resulting from a chemical reaction between a metal oxide and aluminium.
Thermostat is a device which controls the heating or cooling of a substance, by turning the machinery on or off, in order to maintain a constant temperature.
Octahedral molecular geometry (square bipyramidal shape) describes the shape of compounds where six atoms or ligands are symmetrically arranged around a central atom. The sulfur hexafluoride (SF6), with six bonding pairs, is predicted and found to be a regular octahedron. Four of the attachments are positioned in a square plane with 90° bond angles. The remaining two attachments are positioned perpendicular (90°) to the square plane at opposite ends of the central atom. Molecules with an octahedral electron pair geometries have sp3d2 (or d2sp3) hybridization at the central atom.
Oil of vitriol is an obsolete name for sulfuric acid (H2SO4). Very old way of making sulfuric acid is by heating green vitriol (FeSO4*7H2O) to decomposition and collecting the acid vapors evolved.
The term toxicity is very widely used in the safety context. It is used in two contrasting senses: to denote the capacity to cause harm to a living organism, and to indicate the adverse effects caused by a chemical.
Transference number of an ion is the fraction of the total current that is carried by that ion during electrolysis. Different ions carry different fractions of the current because different ions move at different speeds under the same potential gradient. In general, a cation and an anion differ in the amount of current they can carry during electrolysis.
Omega-3 fatty acids are polyunsaturated fatty acids, meaning they contain more than one double bond. The name omega-3 indicates that the first double bond occurs on the third carbon atom (n-3) from the methyl (-CH3) end of the molecule (omega position). The three main omega-3 fatty acids are alpha-linolenic acid (ALA, 18:3n-3), eicosapentaenoic acid (EPA, 20:5n-3), and docosahexaenoic acid (DHA, 22:6n-3). ALA comes from plants. EPA and DHA come from fish.
Similarly, the first double bond in omega-6 fatty acids is located between the sixth and seventh carbon atom (n-6) from the methyl end of the fatty acid (omega end).
