Question

Which of the following statements about propene, CH3CH=CH2, is correct?
Options
A All nine atoms lie in the same plane.
B The compound has a cis and trans isomer.
C There is a total of eight sigma bonds.
Correct Answer
D All the carbon atoms are sp2 hybridized.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Propene (CH3CH=CH2) has 8 sigma bonds (6 C-H bonds and 2 C-C bonds) and 1 pi bond. Not all atoms are in one plane (the CH3 group is tetrahedral). Propene does not show cis-trans isomerism because one carbon of the double bond has two identical H atoms. The terminal carbon (CH3) is sp3 hybridized.

Hint

How many sigma bonds are in propene?
