Question

Which of the following statement is true with respect to H2O, NH3 and CH4? A. The central atoms of all the molecules are sp3 hybridized. B. The H–O–H, H–N–H and H–C–H angles in the above molecules are 104.5º, 107.5º and 109.5º, respectively. C. The increasing order of dipole moment is CH4 < NH3 < H2O. D. Both H2O and NH3 are Lewis acids and CH4 is a Lewis base. E. A solution of NH3 in H2O is basic. In the solution NH3 and H2O act as Lowry-Bronsted acid and base respectively. Choose the correct answer from the options given below:

(A) A, B and C only
(B) C, D and E only
(C) A, B, C and E only
(D) A, D and E only
