Q97 · CSIR NET Chemistry, December 2012
Paper: CSIR NET December 2012 · Subject: Physical Chemistry · Chapter: Quantum Chemistry · Topic: Huckel MO Theory · Marks: 2 · Difficulty: Medium
One molecular orbital of a polar molecule AB has the form $c_A\psi_A + c_B\psi_B$, where $\psi_A$ and $\psi_B$ are normalized atomic orbital's centred on A and B, respectively. The electron in this orbital is found on atom B with a probability of 90% neglecting the overlap between $\psi_A$ and $\psi_B$ a possible set of $c_A$ and $c_B$ is:
(a)$c_A = 0.95,\ c_B = 0.32$
(b)$c_A = 0.10,\ c_B = 0.90$
(c)$c_A = -0.95,\ c_B = 0.32$
(d)$c_A = 0.32,\ c_B = 0.95$
