The simplest cycloalkane has:?
Answer:
Three - cyclopropane.
3. Carbenes.
least number of carbons to form ring must be 3. cyclopropane
three carbon atoms that form a cycloalkane that is a triangle in shape.
What is the smallest polygon?
Think of your basic geometry.
You cannot draw a shape until you have 3 points. It is a triangle.
So you need 3 carbon atoms before you can draw a cyclic compund.
c.3 Carbons = Cyclo-propane. (C3H6)
CH2—CH2
..\.../
..CH2
(Ignore the dots).
3 carbon atoms as that is the lowest number of points needed for a closed ring to be formed.
1 carbon atom would form methane,
2 carbon atoms would form ethene,
3 carbon atoms would form CYCLOpropane which is shaped like a triangle
4 carbon atoms would form cyclobutane, which is shaped like a box, or it could form methyl cyclopropane,
and 5 carbon atome sould form cyclopentane, which is shaped like a pentagon.
The answer is c, three carbons and the cycloalkane is cyclopropane (C3H6).
c. three carbons
