JEE MAIN - Chemistry (2021 - 24th February Evening Shift - No. 12)
The correct shape and $$I - I - I$$ bond angles respectively in $$I_3^ - $$ ion are :
Linear; 180$$^\circ$$
T-shaped; 180$$^\circ$$ and 90$$^\circ$$
Trigonal planar; 120$$^\circ$$
Distorted trigonal planar; 135$$^\circ$$ and 90$$^\circ$$
Explanation
Hybridisation of central $$I$$ in $$I_3^ - $$ is sp3d with 3 lone pair and 2 bond pair.
Shape Linear
