Explain why alcohols and ethers of comparable moelcular mass have different boiling points? |
| Answer» Solution :Alcohols undergo intermolecular H-bonding and hence EXIST as associated moelcules. ETHERS, on the other hand, do not have H atom on the O-atom and hence do not form H-bonds. As a result, ethers exist as dicrete molecules which are held only by weak dipole-dipole attractions. since lesser energy is required to break weak dipole-dipole attactions than to break H-bonds in associated molecules of alcohols, therefore, boiling points of alcohols are MUCH HIGHER than those of ethers of COMPARABLE molecular mass. | |
