Functional groups: A functional group could be an atom or a group of atoms within a molecule that is responsible for its characteristic chemical reactions. Functional groups binding to a central atom in a coordination complex are called ligands. Ammonia is a special case with no carbon atoms.

Functional Groups TABLE OF CONTENTS 1. 0000022204 00000 n One of the most important properties of amines is that they are basic, and are readily protonated to form ammonium cations. For these three functional groups, it is important to remember that the W part has to be considered together with the C=O, since overall they define the functional group. If you don't know the relative values of the pK a 's of the major functional groups, you'll be flying blind in the course.

(If you want bananas to ripen quickly, put them in a paper bag along with an apple - the apple emits ethene gas, setting off the ripening process in the bananas). 0000020230 00000 n Plus, when functional groups are more electronegative than atoms they attach to, the functional groups will become polar, and the otherwise nonpolar molecules containing these functional groups become polar and so become soluble in some aqueous environment. x+TP0134S0 BCc=##=S3SCK=c3\}$c|@ Q endstream endobj 17 0 obj << /Length 52 /Filter [ /FlateDecode ] >> stream Basic knowledge of the structures and polarities of these groups is assumed. 0000038966 00000 n Just as there are primary, secondary, and tertiary alcohols, there are primary, secondary, and tertiary amines. startxref The reactivity of a functional group can be modified by other functional groups nearby. the groups were taken from Abdul Jameel et al . In a ketone, the carbon atom of a carbonyl is bonded to two other carbons. Often when drawing organic structures, chemists find it convenient to use the letter 'R' to designate part of a molecule outside of the region of interest. Knowing functional groups is one of the basic skills required for this course. 48 0 obj <> endobj Another way of thinking of an amide is that it is a carbonyl bonded to an amine. 0000001529 00000 n 0000019095 00000 n 0000015807 00000 n Ammonia is a special case with no carbon atoms.

Suffixes can be combined, as in methylidyne (triple bond) vs. methylylidene (single bond and double bond) vs. methanetriyl (three double bonds). One of the most important properties of amines is that they are basic, and are readily protonated to form, Do not be confused by how the terms 'primary', 'secondary', and 'tertiary' are applied to alcohols and amines - the definitions are different. Note: groups can rotate about a C-C single bond ( only), but not a C=C double ( + )! Much of the remainder of your study of organic chemistry will be taken up with learning about how the different functional groups tend to behave in organic reactions. xb```e`` @(Ud``qkGT#}s2ZzwJxo$6]\9igQtdi(lmQEcR^+MT:zau9_uEx26eO6U/bb|""~!uP9 c/*::ph4 VQsKm 4{n#ae`Y-;AC|^6/lN00;YH9;$5baa 4yDc5.

When the hydrogen atom(s) in NH3 is replaced with R groups, it produces amine. Capsaicin, the compound responsible for the heat in hot peppers, contains phenol, ether, amide, and alkene functional groups. 48 70 0000005010 00000 n The most prominent band in alcohols is due to the O-H bond, and it appears as a strong, broad band covering the range of about 3000 - 3700 cm-1. 0000043311 00000 n 0000013148 00000 n If you need a refresher please turn to your organic chemistry textbook.

Determine and name the longest continuous carbon chain that includes this group. A single compound may contain several different functional groups. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. Functional Groups functional group: an atom, or group of atoms (with specific connectivity), exhibiting identical chemical reactivity regardless of the molecule containing it; the reactivity of individual functional groups dictates the reactivity of the molecule of which they are a part divide organic compounds into classes The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. a) a compound with molecular formula C6H11NO that includes alkene, secondary amine, and primary alcohol functional groups. 4 0 obj << /Linearized 1 /O 6 /H [ 1754 275 ] /L 203812 /E 202164 /N 1 /T 203615 >> endobj xref 4 67 0000000016 00000 n type of proton type of compound chemical shift range, ppm RC H 3 1 aliphatic 0.9 R 2 C H 2 2 aliphatic 1.3 R 3 C H 3 aliphatic 1.5 C=C- H vinylic 4.6-5.9 C=C- H vinylic, conjugated 5.5-7.5 C!
