MCQ
Which of the following phenomenon will occur when two atoms of same spin will react?
- ABonding will not occur.
- BOrbital overlap will not occur.
- CBoth (a) and (b)
- DNone of these.
Explanation:
Same spin electrons in two atoms do not take part in bonding.
Since, they have the same spin, there are strong repulsions due to which bonding and orbital overlap will not occur.

$A.$ For 1 s orbital, the probability density is maximum at the nucleus.
$B.$ For $2 s$ orbital, the probability density first increases to maximum and then decreases sharply to zero.
$C.$ Boundary surface diagrams of the orbitals encloses a region of $100 \%$ probability of finding the electron.
$D.$ $p$ and d-orbitals have $1$ and $2$ angular nodes respectively.
$E.$ Probability density of p-orbital is zero at the nucleus.
