Chapter 24: Problem 12

True or false: The weaker a single bond in a molecule, the greater the chance it will be the site of a reaction (compared to stronger single bonds in the molecule).

Short Answer

Expert verified
True. Weaker single bonds have a lower activation energy and require less energy to break, making them more likely to be the site of a reaction compared to stronger single bonds in the molecule.

Step by step solution

01

Understand bond strength and reactivity

Bond strength refers to the energy required to break a chemical bond between two atoms. Bonds with higher bond strength require more energy to break, while weaker bonds require less energy. On the other hand, reactivity is the tendency of a molecule to undergo a chemical reaction. It is influenced by factors like bond strength, electron density, and molecular geometry.
02

Relationship between bond strength and reactivity

In general, weaker bonds are more likely to be the site of a reaction because they require less energy to break, making it more accessible for a reaction to occur. Reactivity is affected by the activation energy, which is the minimum energy required for a reaction to take place. When a bond has a lower bond strength, it corresponds to a lower activation energy, increasing the likelihood of a reaction happening at that particular bond.
03

Evaluate the given statement

Based on our understanding of bond strength and reactivity from the previous steps, the statement "The weaker a single bond in a molecule, the greater the chance it will be the site of a reaction (compared to stronger single bonds in the molecule)" is True. This is because weaker single bonds require less energy to break and have lower activation energy, making them more likely to be the site of a reaction when compared to stronger single bonds in the molecule.
