Question

Which one of the following has maximum number of nodal planes?

• A. ${\sigma \ast }_{1s}$
• B. ${\sigma \ast }_{{2p}_z}$
• C. ${\pi }_{{2p}_x}$
• D. ${\pi \ast }_{{2p}_y}$

Answer 1

The correct option is B ${\sigma \ast }_{{2p}_z}$

No. of nodal planes in BMOs = no. of nodal planes in combining orbital

No. of nodal planes AGMOs = no. of nodal planes in combining orbital + 1

$A\to 0$

$B\to 1+2=3$

$C\to 2$

$D\to 2$
