Question

Highest occupied molecular orbital of B2+ ion is
a) π*orbital
b) Sigma* orbital
c) π orbital
d) Sigma orbital​

Answer 1

Answer:

pi orbital

Explanation:

bec there is weak pi bond that's why comparative sigma bond

Answer 2

Option (c) Highest occupied molecular orbital of $B2+$ion is  π orbital

Explanation:

• $B2+$  has 10 electrons  

• Its electronic configuration is $sigma (1s), 2 sigma*(1s) ,2 sigma(2s), 2 sigma* (2s) ,2 pi (2p) x1, Pi 2p y1$

• Here unpaired electrons are found and due to the presence of unpaired electrons, the nature is paramagnetic.

• Here the highest occupied molecular orbital is of $\pi$ orbital.
• pi bonds are covalent chemical bonds.
• They can form a double and triple bonds but do not form single bonds.
• They involve complete overlapping of two lobes of atomic orbital with the other.
