Choose the correct pair:
`NH_3` - Trigonal pyramidal
`SF_4` - Tetrahedral

Account for the following: i) 'NF_3' is pyramidal while 'BF_3' is trigonal planar. ii) Bond angle in 'H_2 O' is larger than bond angle in 'H_2 S'.

Choose the correct answer from the brackets given below: 1)General formula of alkene ( C_nH_(2n) , C_nH_(2n+2)

Why is BF_3 planar molecule but NH_3 is pyramidal?

Choose the correct answer. int_(1/3)^1 (x-x^3)^(1/3)/x^4 dx =

Water molecule has a V-shape or bent structure and NH_3 molecule has pyramidal shape both has 4 electron pairs around the central atom. Justify the statement.
