When comparing the boiling point of each of the following pairs, which of the following lists the compound with the highest boiling point first, assuming the same carbon chain length?
a) aldehyde, alcohol
b) ketone, carboxylic acid
c) carboxylic acid, alkane
d) alkane, aldehyde
e) ether, carboxylic acid

C

Explanation:

Carboxylic acid contains a -COOH group which can interact with water via hydrogen bonding. This hydrogen bonding makes it soluble in water and elevates its boiling point as expected for moderately strong non-covalent interaction.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
