Question

Complex [ML5] can exhibit trigonal bipyramidal and square pyramidal geometry. Determine total number of 180&ordm;, 90&ordm; & 120&ordm; L-M-L bond angles.Correct answer is '20'. Can you explain this answer?

Answer

∠120º = 3; ∠90º = 6; ∠180º = 1
→Total = 10

∠90º = 8; ∠180º = 2 ⇒ Total = 10

Answer

Greetings Friend .See I am not an expert but as per my knowledge i checked this question out and got total of 10 as answer and according to me I think the angle is measured even with direction as we do in vectors . So maybe every angle can be counted twice as both in opp. directions .Hope this would help . have a nice day :).

Answer

The total number of 180-degree bond angles in a complex with trigonal bipyramidal or square pyramidal geometry can be determined by considering the number of bond angles in each geometry.

Trigonal bipyramidal geometry has 5 bond angles, with 3 angles of 120 degrees (equatorial positions) and 2 angles of 90 degrees (axial positions). Therefore, the total number of 180-degree bond angles in a complex with trigonal bipyramidal geometry is 0.

Square pyramidal geometry has 6 bond angles, with 5 angles of 90 degrees (equatorial positions) and 1 angle of 180 degrees (axial position). Therefore, the total number of 180-degree bond angles in a complex with square pyramidal geometry is 1.

Answer

2 of 90,3 of 120,1 of 180
