Chapter 7: Noncovalent Interactions and Functional Groups

The shapes of molecules also affect the magnitudes of the dispersion forces between them For example boiling points for the isomers n-pentane isopentane and neopentane (Figure 4) are 36 C 27 C and 9 5 C respectively even though these molecules have the same chemical formula C 5 H 12 and therefore same number of electrons The difference in boiling points suggests that dispersion

Functional Groups in Organic Compounds – Compound Interest

Jan 24 2014A functional group in chemistry is the part of the molecule that gives it its particular reactivity simple molecules that contain the same functional group in their structure can be expected to react in similar ways More complicated chemical molecules may contain more than one functional group within their structure which can sometimes

What is the difference in a Work Group and a Functional

While work groups and functional teams are the same to some people distinctions do exist A work group is made up of members that can represent one unit (functional area) or several units or functional areas Let's look at an example — a work group made up of members from IT customer support and sales

Definition of Carboxyl Group in Chemistry

Carboxyl groups ionize by releasing the hydrogen atom from the -OH group The H + which is a free proton is released Thus carboxyl groups make good acids When hydrogen leaves the oxygen atom has a negative charge which it shares with the second oxygen atom in the group allowing the carboxyl to remain stable even when oxidized
