How many sigma and how many pi bonds are present in the ethene molecule (C2H4)?
a. 4 sigma and 1 pi
b. 4 sigma and 2 pi
c. 5 sigma and 2 pi
d. 5 sigma and 1 pi
The ethene molecule (C2H4) has two carbon atoms connected by a double bond. Each Carbon atom has two hydrogen atoms attached to it. A double bond has 1 pi and 1 sigma bond and a C-H is a sigma bond. So, there is a total of d. 5 sigma and 1 pi
