The yield of the synthesis of diphenylacetylene from stilbene dibromide may be affected by the fact that potassium hydroxide can absorb so much moisture from the air that it looks like a puddle of water. This means that a bottle is never 100 % potassium hydroxide especially after it is opened by multiple students, and not closed quickly and properly. Then the pellets or flakes of potassium hydroxide become sticky and are never completely transferred to the reaction.
1. A solid compound that absorbs so much moisture from the air that it looks like a puddle of water is called .
Select one:
a. deliquescent
b. barometric
c. hygroscopic
d. efilorescent
e. hydroscopic

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
