Question

Assertion :P orbital is dumb-bell shaped. Reason: Electron present in p orbital can have any one of the three values of the magnetic quantum number, i.e 0, +1 or -1.

Read the above assertion and reason and choose the correct option regarding it.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

As we know,
Value of $l=0$ to $n-1$
and
value of $m=-l$ to $+l$
For p-orbitals,
$l=1$ so
$m=-1,0$ and $+1$
