Explain why alcohols have higher boiling points than corresponding alkyl halides. |
|
Answer» Solution :In alkyl HALIDES the electronegativity difference between carbon and halogen atoms is comparatively less than the electro- negativity difference between oxygen and hydrogen atoms in -OH bondin ALCHOLS. Hence-OH in alcohols is more polar than C-X bond in alkyl halides. (3) Therefore intermolecular FORCES in alcohols are stronger and need higher energy to break hydrogen bonds than in alkyl halides. (4) Hence alcohols have higher boiling points than CORRESPONDING alkyl halides. |
