Does 1-propanol expected to have a higher boiling point than ethyl methyl ether

Chemistry

vivado [14]3 years ago
6 0
Indeed it is. Reasons being that the hydrogen bonds in the 1-propanol is difficult to break. Hence, more energy or heat is needed to be applied. Ethyl methyl ether on the other hand doesn't have hydrogen bonds and that explains why it has a lower boiling point.
*try drawing their structural formula, from there you'll be able to differentiate better*

An aluminum cup of 140 cm3 capacity is completely filled with glycerin at 20°C. How much glycerin will spill out of the cup if t
mel-nik [20]

Explanation:

The given data is as follows.

    coefficient of volume expansion of glycerin (\beta) = 5.1 \times 10^{-4} 1/^{o}C

     linear expansion coefficient of aluminum, (\alpha_{A}) = 23 \times 10^{-6} 1/^{o}C  

              Volume = 100 cm^{3}

The increase in volume of the cup will be calculated as follows.

                    \Delta V_{c} = V \times 3 \times \alpha \times \Delta T

                                 = 100 cm^{3} \times 3 \times 23 \times 10^{-6} \times (31 - 20)^{o}C

                                 = 75900 \times 10^{-6} cm^{3}

                                 = 0.0759 cm^{3}

Formula for increase in volume  of glycerine is as follows.

               \Delta V_{g} = V \times \beta_{g} \times \Delta T

                              = 100 cm^{3} \times 5.1 \times 10^{-4} 1/^{o}C \times (31 - 20)^{o}C

                              = 0.5610 cm^{3}

Therefore, volume of glycerin spilled is calculated as follows.

                        \Delta V = \Delta V_{g} - \Delta V_{c}

                                     = (0.5610 - 0.0759) cm^{3}

                                     = 0.4851 cm^{3}

Thus, we can conclude that 0.4851 cm^{3} glycerin will spill out of the cup.
