In Organic Chemistry A Functional Group Is An Atom Or Group Of Atoms
In organic chemistry, a functional group is an atom or group of atoms that determines the compound’s characteristics. For each of the following compounds: 1) give an acceptable name; 2) identify the functional group; and 3) discuss general key chemical properties of the chemical that fire, environmental, health, or safety personnel should know.
a) CH₃CH₂–O–CH₂CH₂CH₂CH₃
b) CH₃CH₂CH(OH)CH₂CH₂OH
c) CH₃–C(=O)–CH₂CH₂CH₂CH₃

Organic chemistry relies heavily on the concept of functional groups, which are key to understanding the behavior and reactivity of organic compounds. Functional groups are specific groups of atoms within molecules that largely dictate the chemical properties and reactions of the compounds they comprise. This paper explores three specific compounds, providing their acceptable names, identifying their functional groups, and discussing pertinent safety and environmental considerations.
The first compound, CH₃CH₂–O–CH₂CH₂CH₂CH₃, is commonly known as ethoxyhexane or ethyl hexyl ether, an ether. The functional group present in this compound is the ether linkage (–O–), which connects two alkyl groups. Ethers are generally characterized as relatively inert compounds with low reactivity under normal conditions. However, they are highly flammable and pose significant fire hazards; for example, diethyl ether has a flash point of -45°C, illustrating its volatility (Atkins & de Paula, 2018). Environmentally, ethers can contribute to photochemical smog when released into the atmosphere. From a health perspective, exposure to ethers like diethyl ether can cause dizziness and respiratory irritation, and they are also considered anesthetics at high doses (Klouda & Pinter, 2016). Proper handling, storage, and ventilation are essential to mitigate these risks.
The second compound, CH₃CH₂CH(OH)CH₂CH₂OH, is known as pentan-1,5-diol, an alcohol. Its functional groups are hydroxyl groups (–OH) attached to the carbon chain. Alcohols are polar molecules with significant hydrogen bonding capacity, influencing their boiling points and solubility in water (Silverstein, Weber, & Kiemle, 2020). In terms of safety, alcohols are generally flammable and can cause skin and eye irritation. They also pose inhalation risks and can be toxic if ingested or inhaled in significant quantities (Fisher & Moulder, 2017). In environmental contexts, alcohols can volatilize readily, yet their oxidized forms can contribute to atmospheric pollution.
The third compound, CH₃–C(=O)–CH₂CH₂CH₂CH₃, is named pentan-2-one, which is a ketone. The functional group here is the carbonyl group (C=O) bonded to two alkyl groups, characteristic of ketones. Ketones are typically characterized by a distinct sweet odor and are commonly used as solvents in cleaning and industrial processes. They are moderately flammable, with flash points generally below room temperature, and pose fire risks (EPA, 2021). Additionally, ketones can be irritating to respiratory pathways and skin upon contact. Environmental concerns include their volatility and potential to contribute to air pollution when emitted indiscriminately (EPA, 2021). Proper containment and ventilation are crucial when handling ketones to prevent fire hazards and health effects.
In conclusion, understanding the nature of functional groups in organic compounds is essential for assessing their chemical behavior and safety. Ethers, alcohols, and ketones each have unique functional groups that influence their flammability, reactivity, and environmental impact, demanding appropriate safety measures during their handling and disposal.
