Question

Out of ch3br and ch3i which has more boiling point and why​

Answer 1

Explanation:

1(a) CH3OH. Strongest intermolecular forces. Only molecules which can hydrogen bond (to each other). ... CH3Br has stronger overall forces of attraction between its molecules than CH3Cl (since boiling point is higher), so temporary dipoles have greater influence on boiling point than permanent dipoles.

Answer 2

Compare boiling point of methyl bromide and methyl iodide

Explanation:

Boiling point

It is the temperature, at which substance starts boiling .

Like boiling point of water is 100 degree celsius .

Boiling point depends on :

Nature and strength of forces between the constituent particles .

"More is the strength , more stronger is the bonding , hence more is the boiling point" .

If we compare  methyl bromide and methyl iodide , methyl iodide has less boiling point ,since Br  is more electronegative, it withdraws more electron towards itself  and hence increase dipole moment  within the atom .

Therefore .it requires more energy to split them up and that indicates  higher boiling point.
