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'.

Account for the following:- H_2O is a liquid while H_2S Is a gas.

The 'O-O-H' bond angle in 'H_2 O_2' is

Bond angle in NH_3 is more than in H_2O . Justify.

Bond angle in is PH_4^+ higher than that in PH_3

The 'H-S-H' bond angle in 'H_2 S' is '92 . 2.whereas the 'H-O-H' bond angle in 'H_2 O' is '.104 .5, why?

In the following question, an Assertion (A) is followed by a corresponding Reason (R). Use the following keys to choose the appropriate answer. Assertion : Bond angle of H_2S is smaller than H_2O in gas phase. Reason : Electronegativity of the central atom increases, bond angle decreases.

Assign the possible reason for the following:- H_2O is less acidic than H_2S .
