Is the following statements are correct ?
(i)Among `NH_3, PH_3, AsH_3, and SbH_3, SbH_3` has smallest bond angle.
(ii)Among `SbCl_3, SbBr_3, and Sbl_3 , Sbl_3` has the largest bond angle.

Answer

5

Explanation

(i)Bond pair-bond pair bond angles in `sp^3d^2` are 12.

(ii)`109^@28'` bond angle is observed only in `CF_4` (tetrahedral geometry)

(iii)`N-=N(~~1.1CÅ)ltFN=NF(~~1.21Å)lt`

`(1.49pm0.004)`
(iv)`BF_3` and `NO_3^(-)` ,both trigonal planar , `NF_3` and `H_3O^+`,both trigonal pyramidal.
(v)Order is `{:(NH_3gtPH_3gtAsH_3gtSbH_3),(106^@6" " 93.8^@ " " 91.83^@ " " 91.3^@):}`
(v)Order is `{:(Sbl_3gtSbBr_3gtSbCl_3),(99^@" " 98.2^@ " " 97.1^@):}`
