these halides are ionic crystalline halides. lithium halides are less ionic than sodium halides why?

Alkali metals combine readily with halogens to form ionic halides M + X - . For example, Reactivity of alkali metals with halogen increases down the group because of corresponding increase in electropositive character (decrease in ionization energy). All metal halidesh..

Halides - The elements of this group form a variety of halides. The important features regarding the halides are: (i) Since fluorine is more electronegative than oxygen, its compounds with oxygen are called fluorides. For e.g., F 2 O is written as OF 2 and is named as ..

Group 15 elements form two series of halides of the type MX 3 , (trihalides) and MX 5 , (pentahalides). The trihalides are formed by all the elements while pentahalides are formed by all the elements except nitrogen. Nitrogen cannot form pentahalides due to the absence of vacant d-o..

Al, Ga, In and Tl react with halogens to give binary halides. All the halides of group 13 elements are known except Tl(III) iodide. The fluorides are ionic and have high melting points. The chlorides, bromides and iodides are essentially covalent compounds with low me..

Alkyl halides on treatment with ethanolic solution of sodium cyanide or potassium cyanide give alkyl cyanides. ..

When chloro or bromoalkanes are heated with a concentrated solution of sodium iodide in acetone, iodoalkanes are obtained. This method is useful for preparing iodoalkanes. ..

Alkyl halides on treatment with ethanolic solution of sodium cyanide or potassium cyanide give alkyl cyanide..

The formation of cyanide or isocyanides from alkyl halides involves nucleophilic substitution reaction. The cyanide ion From the hybrid structure, it is evident, that the cyanide is capable of attacking the molecule through C atom as well as through N atom. Such a nucleophilic species whi..

The most important acyl halides are acyl chlorides because they are more easily prepared, more stable and less expensi..
