Question

Explain order of reactivity of alkyl halides towards alkyl halides

Answer 1

★ HALIDES:-

→ Except Beryllium halide all other halides are ionic in nature.

→ Beryllium halides are covalent in nature and soluble in organic solvents.

→ In the normal temperature or solid state they exhibit chain structure (polymer).

→ At vapour phase they form chloro bridged dimer.

→ At temperature of 1200K they form monomer.

→ Tendency to form halide hydrates decreases down the group.

→ For calcium, barium, strontium dehydration of hydrated chlorides, bromides, iodides can be achieved by heating.

→ Be and Mg undergo hydrolysis on heating.
