How to Name Acid Chlorides Using IUPAC Rules

TL;DR

To name acid chlorides using IUPAC nomenclature, identify the longest carbon chain and replace 'acid' with 'acyl' before adding the halide suffix, such as 'chloride' for chlorine. Consider substituents and their positions, naming them in alphabetical order. For example, 3-methylbutanoyl chloride indicates a four-carbon chain with a methyl group on the third carbon.

Transcript

in this video we're going to focus on naming acid halides so how can we name this compound so this is an acid bromide but because we have a total of two carbons which is associated with ethane this is going to be called ethanol bromide since we have a bromine atom attached to it the common name for this particular acid halide is acetal or rather ac...

Key Insights

• 🫀 Acid halides are named based on the number of carbon atoms in the chain and the type of halogen attached.
• 👥 The names of acid halides can change based on the presence of substituents or functional groups.
• 😋 Naming rules differ when acid halides are attached to benzene or cyclohexane rings.

Questions & Answers

Q: How do you name an acid halide with a two-carbon chain and a bromine atom?

This would be called ethanol bromide since it is an acid bromide with a two-carbon chain and a bromine atom attached. The common name for this acid halide is acetal or acetyl bromide.

Q: What is the naming convention for an acid halide with a three-carbon chain and a fluoride atom?

In this case, the acid halide would be called propanol fluoride, as it has a three-carbon chain and a fluoride atom attached.

Q: How would you name an acid chloride with a methyl group on carbon 3 and a four-carbon chain?

The name for this molecule would be 3-methylbutanol chloride, as it has a methyl group on carbon 3, a four-carbon chain, and a chloride atom.

Q: How do you name an acid chloride with a methyl group, bromine atom, and chlorine atom?

This acid chloride would be named as two bromo, three methyl pentanol chloride since it has a methyl group, a bromine atom, a chlorine atom, and a five-carbon chain.
