d.

Verified step by step guidance

Examine the structure of the compound provided in the image. Look for the presence of a carbonyl group (C=O), which is a characteristic feature of both aldehydes and ketones.

Determine the position of the carbonyl group within the molecule. If the carbonyl group is attached to a terminal carbon (at the end of the carbon chain), the compound is an aldehyde. If it is attached to a non-terminal carbon (within the chain), the compound is a ketone.

Check for any additional groups or substituents attached to the carbonyl carbon. This can help confirm whether the compound is an aldehyde or a ketone.

Recall that aldehydes typically have the general formula R-CHO, where R is a hydrocarbon group or hydrogen, and ketones have the general formula R-CO-R', where R and R' are hydrocarbon groups.

Based on the analysis of the structure and the position of the carbonyl group, classify the compound as either an aldehyde or a ketone.

Key Concepts

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

Aldehyde

An aldehyde is an organic compound characterized by the presence of a carbonyl group (C=O) at the end of a carbon chain. The general formula for aldehydes is RCHO, where R represents a hydrocarbon group. Aldehydes are typically more reactive than ketones due to the accessibility of the carbonyl group, making them important in various chemical reactions and synthesis.

Ketone

A ketone is an organic compound that contains a carbonyl group (C=O) situated between two carbon atoms, making it distinct from aldehydes. The general formula for ketones is RC(=O)R', where R and R' are hydrocarbon groups. Ketones are generally less reactive than aldehydes and are commonly found in solvents and as intermediates in organic synthesis.

Carbonyl Group

The carbonyl group is a functional group consisting of a carbon atom double-bonded to an oxygen atom (C=O). It is a key feature in both aldehydes and ketones, influencing their chemical properties and reactivity. The position of the carbonyl group within a molecule determines whether it is classified as an aldehyde (terminal) or a ketone (internal), which is crucial for identifying these compounds.
