हिन्दीFor a molecule of type \( \text{AB}_5 \) having no lone pairs on the central atom (such as \( \text{PCl}_5 \)), the molecular geometry and the bond angles present are:
Correct answer · Option 2
Trigonal bipyramidal; \( 120^\circ \) and \( 90^\circ \)
Explanation
\( \text{AB}_5 \) with 5 electron pairs and no lone pair forms a trigonal bipyramidal geometry with bond angles of \( 120^\circ \) (equatorial) and \( 90^\circ \) (axial-equatorial).
