Question

arrange the following according to. melting point CH3Cl,CH3Br,CH3I,CH3F​

Answer 1

Answer:

Explanation:

melting point inversely proportional to  covalent character

cc directly proportional to anion size

which means melting point is inversely for anion size for high melting point

decreasing order is 1234

Answer 2

Answer: The electronegativity difference between the halogens like F, I, Cl, and Br and carbon is proportional to the bond length.

Explanation: Fluorine is the most electronegative molecule. The Melting point is inversely proportional to electronegativity. so  CH3​F<CH3​Cl<CH3​Br<CH3​I.

Hence, the final answer for decreasing the order of CH3Cl, CH3Br, CH3I, and CH3F is CH3​F < CH3​Cl < CH3​Br < CH3​I.
