The species having bond angle of `90^o` is
1)`SO_3`
2) `SF_6`
3) `SF_4`
4) `NH_4^+`

Find the number of species having bond angle less than 109^(@)28' NH_(3),PH_(3),SiH_(4),NH_(4)^(+),PF_(3),NH_(2)^(-),SO_(3),NO_(2)^(+),"CCl"_(4),H_(2)O,H_(2)S,SO_(4)^(2-)

Which one of each of the following pairs is expected have the larger bond angle ? (1) H_2O and NH_3 (2) SF_2 and BeF_2 (3) BF_3 and BF_4^(-) (4) PH_3 and NH_3 (5) NH_3 and NF_3

Arrange the following sets of molecules in the decreasing order of bond angle : (i) SF_(6), C Cl_(4), H_(2)O, NH_(3) (ii) CH_(4), NH_(3), H_(2)O, BF_(3) (iii) AlCl_(3), H_(2)S, BeH_(2), H_(2)O

Give bond angles in H_(2)O, CH_(4) and SF_(6) molecules.

The bond angle and % of d-character in SF_(6) are

Likely bond angles of SF_(4) molecule are :
