Lab #4 May 26‚ 2015 Diels Alder Reaction Introduction: Diels Alder Reaction is the reaction of a diene with a species capable of reacting with the diene‚ the dienophile. A diene is a hydrocarbon that contains two carbon double bonds‚ while a dienophile is an electron-deficient alkene. The Diels-Alder is also called a [4+2] cycloaddition because a ring is formed by the interaction of four pi electrons of the alkene with two pi electrons of the alkene or alkyne. The product of the Diels-Alder

EFT4 TASK 5 Part A: Describe how to introduce the concept of surface area of a cube to students in grades 5 and 6. I would introduce the concept of surface area of a cube to 5th and 6th grade students by starting off the lesson with a visual representation. I would place a picture of a cube at the front of the class and explain to students that all sides are equal. I would take out a ruler and measure the sides so that students understand that the sides are equal. The picture would be as follows:

Collinear is passing through or lying on the same staright line. Coplanar is lying on or occurring in the same plane. Define Non-Collinear Points The points which do not lie on the same line are known as Non-Collinear Points Below diagram represent‚ Non-Collinear Points P‚ Q‚ R & S. In the above Diagram‚ Points P‚ Q‚ R & S doesn not falls on the same line and Hence they are called Non-Collinear Points. | Coplanar Definition of Coplanar * A set of points‚ lines‚ line
