The strongest intermolecular interactions between acetic acid (CH.COOH) molecules arise from:a) dipole-dipole forces b) ion-dipo
le interactions. c) London dispersion forces. d) hydrogen bonding. Draw two molecules of acetic acid to demonstrate this intermolecular interaction.
1 answer:
Answer:
hydrogen bonding
Explanation:
Intermolecular forces hold molecules of a substance together in a particular state of matter. In acetic (ethanoic) acid, the strongest intermolecular force is hydrogen bonding.
Hydrogen bonding leads to dimerization and high boiling points. An image showing dimerization of acetic acid is shown in the image attached.

Answer:
A) 0.065 M is its molarity after a reaction time of 19.0 hour.
B) In 52 hours will react 69% of its initial concentration.
Explanation:
The reaction is first order in :
Initial concentration of =
a) Final concentration of after 19.0 hours=
t = 19.0 hour = 19.0 × 3600 seconds ( 1 hour = 3600 seconds)
Rate constant of the reaction = k =
The integrated law of first order kinetic is given as:
0.065 M is its molarity after a reaction time of 19.0 h.
b)
Initial concentration of =
Final concentration of after t =
Rate constant of the reaction = k =
The integrated law of first order kinetic is given as:
t = 185,902.06 s = ≈ 52 hours
In 52 hours will react 69% of its initial concentration.
