QUESTION:
Draw and name alkenes, and calculate their elements of unsaturation. Name geometric isomers using both the E-Z and cis-trans systems.
ANSWER:Step 1 of 3
(a)The number of elements of unsaturation in a hydrocarbon is given by:
Where C, N, H and X are the number of carbon, nitrogen, hydrogen and halogen.
Three double bonds and one ring make 4 elements of unsaturation.
Substituting in the equation,
On further solving,
Hence, the number of hydrogen atoms is 10.
