Vedclass · Answer

(D) For $CH_4$ (tetrahedral),there are $6$ bond angles of $109^\circ 28'$.For $SF_6$ (octahedral),there are $12$ bond angles of $90^\circ$.For $IF_7$ (pentagonal bipyramidal),there are $10$ bond angles of $90^\circ$ (between axial and equatorial bonds).For $IF_5$ (square pyramidal),the structure has $1$ lone pair. The bond angles between the equatorial $F$ atoms and the axial $F$ atom are $90^\circ$. There are $4$ such angles. The angles between equatorial $F$ atoms are also $90^\circ$. There are $4$ such angles. Total $90^\circ$ angles = $8$. However,due to the lone pair,the bond angles are distorted from $90^\circ$. Thus,$IF_5$ is not correctly matched.
