Question
Chemistry Question on Chemical bonding and molecular structure
According to MOT,C2 molecule has
A
onesandoneπ−bond.
B
only two π−bonds.
C
only two s−bonds.
D
onesandtwoπbonds.
Answer
only two π−bonds.
Explanation
Solution
C2(12)=s1s2,s∗1s2,s2s2,s∗2s2,π2px2≈π2py2 C2 has two pairs of electrons in π2pxandπ2py therefore, it has only two π-bonds.
