General Introduction. The two functional groups I deal with here are the C,C double bond and the C,C triple bond. In each case the group is named by changing the letter a in the suffix ane to e for the double bond and to y for the triple bond.otes: 1  Examples 1 and 2 show the use of E/Z for routine alkene structures for which cis/trans could have been used. 2  Examples 5 and 6 show how the rules require you to move down the chain away from the stereocentre (the double bond) until a difference is found. 3  Example 6 illustrates that the functional group named as a prefix takes precedence in ...
compressive strength Definition. The resistance capacity of any material, but especially structural members, to crushing force. Compressive strength is usuallyexpressed as the maximum number of pounds per square inch that can be resisted without failure.
The resistance of a material to breaking under compression. Compare with tensile strength. Example sentences. 1  The compressive strength of a material is calculated as the pounds per square inch required to rupture the specimen or deform it to a given percentage of its height.2  They have a high compressive strength and fair resistance to erosion and scratch abrasion.xample sentences. 1  The compressive strength of a material is calculated as the pounds per square inch required to rupture the specimen or deform it to a given percentage of its height.
