Compared to a hydrocarbon chain where all the carbon atoms are linked by single bonds, a hydrocarbon chain with the same number of carbon atoms but with one or more double bonds will ________.
A) be more flexible in structure
B) be more constrained in structure
C) be more polar
D) have more hydrogen atoms

Question

Quizplus · Accepted Answer

Double bonds introduce rigidity into the hydrocarbon chain, limiting its flexibility and making it more constrained in structure. The presence of double bonds also reduces the number of available hydrogen atoms, so option D is incorrect. The polarity of the hydrocarbon chain is not affected by the presence of double bonds, so option C is also incorrect.
