Give the mechanistic symbols (SN1, SN2) that are most consistent with each of the following statements (a) Methyl halides react with sodium ethoxide in ethanol only by this mechanism. (b) Unhindered primary halides react with sodium ethoxide in ethanol mainly by this mechanism. (c) The substitution product obtained by solvolysis of tert-butyl bromide in ethanol arises by this mechanism. (d) Reactions proceeding by this mechanism are stereospecific (e) Reactions proceeding by this mechanism involve carbocation intermediates (f) This mechanism is most likely to have been involved when the products are found to have a different carbon skeleton from the substrate. (g) Alkyl iodides react faster than alkyl bromides in reactions that proceed by these mechanisms.

your answer would be “dry”

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.
