Arrange the following in the increasing order of their boiling point and give a reason for your ordering : "Propan -1-ol, propan - 1, 2, 3 - triol, propan -1, 3 - diol, propan - 2- ol" |

Answer» Solution :`2^(@)` alcohols have lower BOILING points than `1^(@)-` alcohols due to a corresponding decrease in the extent of H - BONDING because of steric hindrance. Therefore Propan -1 ol has higher boiling point than Propan -2- ol. Hydrogen group increases, boiling point also increases. `therefore"Overall increasing ORDER of boiling points is,"` `"propan -2- ol" LT " Propan -1- ol" lt " propan 1,3 - diol" lt "propan -1, 2, 3- triol"` |
