Question

Statement-1. All $p$-orbitals have only one angular node.
Statement-2. The number of radial nodes depend upon the Principal quantum number only.

• A. Statement-1 is True, Statement-2 is True, Statement-2 is the correct explanation for Statement-1.
• B. Statement-1 is True, Statement-2 is True, Statement-2 is Not a correct explanation for Statement-1.
• C. Statement-1 is True, Statement-2 is False.
• D. Statement-1 is False, Statement-2 is True

Answer 1

The correct option is C Statement-1 is True, Statement-2 is False.

Number of angular nodes = $l$. Hence, for $p$-orbital it is always 1 and it does not depend on the Principal quantum number.

The number of radial nodes depends on $‘n^{\prime }$ and $‘l^{\prime }i.e.,(n-l-1)$ and hence it depends on both $n$ and $l$.
