During an exothermic reaction, H for the reactants was 890 kJ/mol. Which of the following statements is correct about the H for the products and the comparison of the energy in bonds?
Select one:
a. It is less than 890 kJ/mol, and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.
b. It is less than 890 kJ/mol, and the amount of energy required to break bonds is less than the amount of energy released in forming bonds.
c. It is greater than 890 kJ/mol, and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.
d. It is greater than 890 kJ/mol, and the amount of energy required to break bonds is less than the amount of energy released in forming bonds.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
