Sodium hydride is the chemical compound with the empirical formula Na H.This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis.NaH is a saline (salt-like) hydride, composed of Na + and H − ions, in contrast to molecular hydrides such as borane, silane, germane, ammonia, and methane.
Sodium amide is a handy reagent for the Chichibabin reaction but handling it can be dangerous and caution is advised. [4] σ-adduct (Meisenheimer adduct) formation; Evidence indicates that before addition of the amino group, the ring nitrogen atom is sorbed onto the surface of sodium amide and the sodium cation forms a coordination complex.

Group 1: Alkali metals Reaction of sodium (Na) and water Reaction of potassium (K) in water. The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.
How to make basic iced tea. To make a concentrated tea base, steep four to six standard-size tea bags (or the equivalent in loose tea) in two cups of freshly-boiled (but not boiling), hot water ...
The hydride adds to an electrophilic center, typically unsaturated carbon. Hydrides such as sodium hydride and potassium hydride are used as strong bases in organic synthesis. The hydride reacts with the weak Bronsted acid releasing H 2. Hydrides such as calcium hydride are used as desiccants, i.e. drying agents, to remove trace water from ...
Other strong non-nucleophilic bases are sodium hydride and potassium hydride. These compounds are dense, salt-like materials that are insoluble and operate by surface reactions. These compounds are dense, salt-like materials that are insoluble and operate by surface reactions.
This iced tea hack only requires two ingredients: jam and tea. ... Use any kind of bagged or loose-leaf tea and any kind of store ... Start by brewing your tea in a mug with 6 ounces of hot water ...
Iced tea can be brewed by placing tea (bags or loose-leaf) in a large glass container with water and leaving the container in the sun for hours. This often results in a smoother flavor. An advantage is that sun tea does not require using electricity or burning fuel, thus saving energy. Sun tea is sometimes served with syrup or lemon.
