Capitolo 9, Problema 8b
The drawing below shows the overlap of two hybrid orbitals to form a bond in a hydrocarbon. (b) Which of the following could be the identity of the hydrocarbon: (i) CH4, (ii) C2H6, (iii) C2H4, or (iv) C2H2?
Guida verificata passo dopo passo1
Identify the type of hybrid orbitals shown in the diagram. The diagram shows the overlap of two sp hybrid orbitals.
Recall the types of bonds formed by different hybridizations: sp hybridization forms a triple bond or a single bond with two lone pairs, sp2 hybridization forms a double bond, and sp3 hybridization forms a single bond.
Determine the type of hydrocarbon that can have sp hybridization. Hydrocarbons with sp hybridization include those with triple bonds, such as acetylene (C2H2).
Analyze the given options: (i) CH4 (sp3 hybridization), (ii) C2H6 (sp3 hybridization), (iii) C2H4 (sp2 hybridization), and (iv) C2H2 (sp hybridization).
Conclude that the hydrocarbon with sp hybridization, which matches the diagram, is C2H2.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Hybridization
Hybridization is the process of combining atomic orbitals to form new hybrid orbitals that can accommodate bonding. In hydrocarbons, carbon typically undergoes sp3, sp2, or sp hybridization, depending on the number of bonds it forms. This concept is crucial for understanding the geometry and bonding characteristics of molecules.

Hybridization
Types of Hydrocarbons
Hydrocarbons are organic compounds consisting solely of carbon and hydrogen. They can be classified into alkanes (single bonds), alkenes (at least one double bond), and alkynes (at least one triple bond). Identifying the type of hydrocarbon is essential for determining its structure and reactivity, which is relevant to the question.

Bond Formation
Bond formation occurs when atomic orbitals overlap to create a stable connection between atoms. The image depicts the overlap of hybrid orbitals, indicating the formation of a sigma bond. Understanding how bonds form helps in predicting the molecular structure and properties of the hydrocarbon in question.

The molecule shown here is called furan. It is represented in the typical shorthand way for organic molecules, with hydrogen atoms not shown, and each of the four vertices representing a carbon atom. e. The bond angles in furan are much smaller than those in benzene. The likely reason is which of the following? i. The hybridization of the carbon atoms in furan is different from that in benzene. ii. Furan does not have another resonance structure equivalent to the one shown here. iii. The atoms are forced to adopt smaller angles in a five-membered ring than in a six-membered ring. [Section 9.5]
