The discussion centers on identifying the hydrocarbon that differs in structure despite having the same atoms as the others listed. The hydrocarbons in question are cyclobutane, 1-butene, 2-butene, cyclobutene, and methylcyclopropane. The initial guess points to cyclobutane, but upon further analysis, cyclobutene is identified as the exception due to its formula C4H6, which indicates two degrees of unsaturation from both a cycle and a double bond. This highlights the importance of structural representation in understanding the differences among hydrocarbons. The conclusion emphasizes that structural variations significantly impact the properties of hydrocarbons.

Homework Statement


The following hydrocarbons have different structures but the same atoms except for one. Which of them is this exception and what is the difference?
a)cyclobutane
b)1-butene
c)2-butene
d)cyclobutene
e)methylcyclopropane

Homework Equations


Which of them is this exception and what is the difference?

The Attempt at a Solution


At a first glance, i would say (a)
 
Physics news on Phys.org


Why don't you take a second glance and draw out the structure/chemical-formulae to find out.

ok, i think it's (d) with the formula C4H6
 


Looks good, 'd' has 2 degrees of unsaturation---the cycle and the double bond.
