Textbook Question

Draw a Lewis structure, and classify each of the following compounds. The possible classifications are as follows:
alcohol
ether
ketone
aldehyde
carboxylic acid
alkene
(h)
(i)

Verified step by step guidance

Step 1: Identify the functional groups in each compound. For compound (h), the 'CHO' group indicates the presence of an aldehyde functional group. For compound (i), the 'CH2OH' group indicates the presence of an alcohol functional group.

Step 2: Draw the Lewis structure for compound (h). Start by drawing the pentane ring, then add the aldehyde group. The aldehyde group consists of a carbonyl group (C=O) with a hydrogen atom attached to the carbon.

Step 3: Draw the Lewis structure for compound (i). Start by drawing the pentane ring, then add the alcohol group. The alcohol group consists of an -OH group attached to a carbon atom.

Step 4: Classify compound (h) as an aldehyde based on the presence of the 'CHO' group, which is characteristic of aldehydes.

Step 5: Classify compound (i) as an alcohol based on the presence of the 'CH2OH' group, which is characteristic of alcohols.

Key Concepts

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

Lewis Structure

A Lewis structure is a diagrammatic representation of a molecule showing how the valence electrons are arranged among the atoms in the molecule. It helps in visualizing the bonding between atoms and the lone pairs of electrons that may exist. For organic compounds, it is crucial to depict the connectivity and arrangement of atoms, especially for functional groups.

Aldehyde Functional Group

An aldehyde is an organic compound containing a carbonyl group (C=O) bonded to at least one hydrogen atom. The general structure is R-CHO, where R is a hydrocarbon group. Aldehydes are characterized by the presence of the carbonyl group at the end of a carbon chain, which is crucial for their reactivity and classification in organic chemistry.

Functional Group Classification

In organic chemistry, compounds are classified based on their functional groups, which are specific groups of atoms within molecules that determine the chemical properties of those molecules. Common functional groups include alcohols, ethers, ketones, aldehydes, carboxylic acids, and alkenes. Identifying the functional group is essential for predicting the reactivity and properties of the compound.
