हिन्दीFor an \( \text{AB}_5 \) molecule having trigonal bipyramidal geometry with zero lone pairs (such as \( \text{PCl}_5 \)), what is the total number of distinct \( \text{B}-\text{A}-\text{B} \) bond angles that are strictly equal to \( 90^\circ \)?
Correct answer · Option 4
\( 6 \)
Explanation
In trigonal bipyramidal geometry, each of the 2 axial bonds forms a \( 90^\circ \) angle with the 3 equatorial bonds, giving \( 2 \times 3 = 6 \) angles of \( 90^\circ \).
