Hydrocarbon X is an alkene. One molecule of X contains 24 atoms in total.
Calculate the number of carbon atoms in one molecule of X.
Give the molecular formulae of X and of the alkane with the same number of carbon atoms as X.
A student changes the displayed formula of X by replacing the C=C\text{C}=\text{C}C=C bond with a C−C\text{C}-\text{C}C−C bond but makes no other change. The student claims that the result is a correct displayed formula for the alkane.
Evaluate the student's claim.
