question_answer 1)

Considering X-axis as the intemuclear axis, which out of following will not form a sigma bond and why? (a) 1s and 1s (b) 1s and \[2{{p}_{x}}\] (c) \[2{{p}_{y}}\] and \[2{{p}_{y}}\] (d) 1s and 1s

Answer:

Only (c) will not form sigma bond because taking X-axis as the intemuclear axis, there will be sidewise overlap between \[2{{p}_{y}}\] and \[2{{p}_{y}}\] orbitals forming Ti-bonds.
