Boiling points of alcohols table
WebThis increases their boiling and melting point. Straight-chained alcohol molecules are able to form greater dispersion forces due to a greater surface area between molecules. As a result, straight-chain alcohols usually have higher melting and boiling point than their isomers. Table: list of common alcohols and their boiling points. WebThe table below shows the comparison of the boiling points of alcohols and equivalent alkanes in terms of carbon chain length. Volatile – the ease at which a liquid evaporates. Van der Waals interactions . 5 The boiling points depend on intermolecular forces (between molecules). Alkanes only have van der
