I’m always open to further revisions, so if there’s a functional group that’s missing that you think should be included, let me know in the comments below.Įnjoy Compound Interest’s posts? Consider supporting Compound Interest on Patreon! Organic molecules are featured in many of the site’s graphics – see if you can spot any of these functional groups in previous posters! At a simple level, molecules with a certain functional group can be predicted to react in similar ways with other substances. If you haven’t, it’s a useful tool to decode the different parts that make up molecules in organic chemistry.Īll carbon-based (organic) molecules contain functional groups – some more than one of them – and they’re what gives molecules their particular reactivity. The purpose of this chart will be clear if you’ve got a background in chemistry. Actually, a functional group is an atom or a group of atoms with characteristic chemical and physical properties. They determine a molecule’s geometry, physical properties, and reactivity. In particular, sulfur-containing functional groups are much better represented, and a few additional nitrogen-containing groups have crept in. Table of Contents Functional groups in organic chemistry Functional groups in organic chemistry Functional groups are structural features distinguish one organic molecule from another. While this chart still doesn’t claim to be exhaustive, it contains almost double the number of functional groups as the original chart (40 vs. This week, I finally got around to doing that! of C’s attached to the other end of the functional group (including the carbonyl carbon)- name using the prefixes (second part of name)-from carboxylic acid.Since I published my original functional groups chart back in 2014, I’ve had a fair few requests to expand it to include more functional groups. Use your problem solving skills and the answers in the table above to fill in the blank boxes.

Give fruit their pleasant ‘fruity’ smell, they have lower boiling points than alcohols and carboxylic acids of a similar size.ġ.Locate the functional group and the carbonyl carbon.Ģ.Look at the C’s attached to the oxygen in the functional group- name using the prefixes (first part of name)- from alcoholģ.Look at the total no.

Called an esterification reaction, also condensation reaction.

Esters are formed by a reaction between a carboxylic acid and an alcohol.

Uses: Found in many natural & synthetic drugs.

Knowing the functional groups is a must in organic chemistry and in this post, we will go over the structure and interesting applications of the most common functional groups in organic chemistry.

Weak acids, relatively high boiling points A functional group is an atom or a group of atoms that are responsible for the physical and chemical properties of the molecule.

There are other functional groups that contain. However solubility decreases with longer chains. Use proper naming conventions for aldehyde, ketone, carboxylic acid, and ester- and ether-containing molecules. For each IOD that includes this Module, a table is defined in which the permitted Functional Group Macros and their usage is specified.

Polar –OH group allows alcohol to dissolve in water.

This is required for students to quickly. Knowing the functional groups well is one of the fundamental skills required for this course. A summary of common functional groups is included in Table 2.2.

Boiling points increase as the size of the molecule increases. F unctional groups are the most reactive parts in organic compounds and determine the major properties of compounds.

Ethanol, CH3CH2OH present in wine, beer, etc.

Number chain from the end of the closest carbon to the functional group.

Halogen – Group VII elements eg: Cl, Br, IĮxample: chloromethane, CH3Cl (anaesthetic).

The bond, atom, or group of atoms which gives a molecule its specific properties is called its functional group.ġ. Understand what functional groups are, and explore the functional groups list, including alkyl, ester, and aldehyde functional group.
