Question 1
According to VB theory, a double bond that results from the sharing of four electrons consists of:
◦ 2 sigma bonds
◦ one sigma and one pi bond
◦ one sigma bond
◦ two pi bonds
◦ one sigma bond and one coordinate bond
Question 2
According to VB theory, sigma bonds are:
◦ always present in double bonds
◦ formed only by
p orbitals
◦ formed only by hybrid orbitals
◦ formed only by
s orbitals
◦ formed only by unhybridized orbitals
