Concept explainers
(a)
Interpretation:
The given set of compounds has to be arranged in the increasing order of boing point.
Concept introduction:
The boiling points of carboxylic acids are higher than those of alcohol or
Intermolecular hydrogen bonding will increase the boiling point of an organic compound.
Carboxylic acids can form dimers in which hydrogen bonds form between two carboxyl groups this will also increase their boiling point.
Increasing order of boiling point of some organic compounds with similar molecular weight is shown below,
The better hydrogen bond capability of a molecule will increase its boiling points.
(b)
Interpretation:
The given set of compounds has to be arranged in the increasing order of boing point.
Concept introduction:
The boiling points of carboxylic acids are higher than those of alcohol or aldehydes of similar relative molecular mass due to intermolecular hydrogen bonding.
Carboxylic acids can form dimers in which hydrogen bonds form between two carboxyl groups this will also increase their boiling point.
Intermolecular hydrogen bonding will increase the boiling point of an organic compound.

- 75.0 grams of an unknown metal was heated to 95.0°C, it was then placed into 150.0 grams of water at23.1°C, when the metal and water reached thermal equilibrium, the temperature was 27.8°C. Calculatethe specific heat of the metal.

- Zeolites: environmental applications.arrow_forward" is The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: :Ö: HO + Bicarbonate is crucial for the control of body pH (for example, blood pH: 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.arrow_forwardWhich of these is the best use of a volumetric flask? measuring how much liquid it contains delivering a precise amount of liquid to another container holding solutions making solutions of precise concentrationarrow_forward
