Textbook Question

What is chemically nonsensical about this structure?

Verified step by step guidance

Identify the atoms and their valence electrons in the structure.

Determine the number of bonds each atom can form based on its valence electrons.

Check if the number of bonds around each atom matches its valence requirements.

Analyze the structure to see if any atom has more or fewer bonds than it should.

Conclude what is chemically nonsensical about the structure based on the valence electron rules.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Valency of Carbon

Carbon has a valency of four, meaning it can form four covalent bonds with other atoms. In the given structure, the carbon atoms are shown to be bonded in a way that suggests they are forming more bonds than their valency allows, leading to an unstable or impossible configuration.

Bonding Types

There are different types of chemical bonds, including single, double, and triple bonds. The structure in question appears to have an incorrect representation of these bonds, as it suggests an unrealistic arrangement of double and single bonds that does not adhere to the rules of bonding in organic chemistry.

Structural Representation

Chemical structures are represented using specific conventions that indicate how atoms are connected. The nonsensical aspect of the structure may arise from improper use of these conventions, such as incorrect placement of hydrogen atoms or misrepresentation of the connectivity between carbon atoms, leading to confusion about the actual molecular structure.
