The orbital angular momentum is given by: \[ L = \frac{\sqrt{l(l+1)}h}{2\pi}. \] For an \(s\)-orbital, \(l = 0\). Substituting \(l = 0\): \[ L = \frac{\sqrt{0(0+1)}h}{2\pi} = 0. \]
Final Answer: \( \boxed{0} \).
Consider the reaction given below:

\(\text{A gives positive Fehling's test. Choose the correct relation}\).

Which of the following statement is true with respect to H\(_2\)O, NH\(_3\) and CH\(_4\)?
(A) The central atoms of all the molecules are sp\(^3\) hybridized.
(B) The H–O–H, H–N–H and H–C–H angles in the above molecules are 104.5°, 107.5° and 109.5° respectively.
(C) The increasing order of dipole moment is CH\(_4\)<NH\(_3\)<H\(_2\)O.
(D) Both H\(_2\)O and NH\(_3\) are Lewis acids and CH\(_4\) is a Lewis base.
(E) A solution of NH\(_3\) in H\(_2\)O is basic. In this solution NH\(_3\) and H\(_2\)O act as Lowry-Bronsted acid and base respectively.

If for \( 3 \leq r \leq 30 \), \( ^{30}C_{30-r} + 3 \left( ^{30}C_{31-r} \right) + 3 \left( ^{30}C_{32-r} \right) + ^{30}C_{33-r} = ^m C_r \), then \( m \) equals to_________
