Organic molecules with only hydrogens and five carbon atoms can have different structures in all of the following ways except
A) by branching of the carbon skeleton.
B) by varying the number of double bonds between carbon atoms.
C) by varying the position of double bonds between carbon atoms.
D) by forming a ring.
E) by forming enantiomers.

Question

Quizplus · Accepted Answer

Organic molecules with only hydrogens and five carbon atoms cannot form enantiomers as they do not have a chiral center. All five carbon atoms are connected to each other in a single chain, and none of them have four different groups attached to them, which is necessary for chirality. Therefore, enantiomers are not possible in this scenario. A, B, C, and D are all correct ways in which the structures of these molecules can vary.
