State reason:- Bond angle of` PF_3` is greater than `NH_3`

Bond angle in NH_(3) is more than in PH_(3). Explain.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I: van der Waals’ constant ‘b’ of N_2 is greater than that of NH_3 Statement - II: Molecular Size of N_2 is smaller than that of NH_3 .

The bond angle in NF_3 (102.3^@) is smaller than NH_3 (107.2^@) . This is because of

The bond angles in PH_(4)^(+) are greater than that in PH_(3) - why ?

The bond angle in NF_(3)(102.^(@)) is smaller than NH_(3)(107.^(@)) . This is because-

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I: van der Waals constant 'a' of NH_3 is greater than that of N_2 . Statement - II: intermolecular force of NH_3 is greater than that of N_2 because NH_3 involves intermolecular H-bond.

State whether True or False:- The angle of refleciton becomes greater than the angle of incidence.

NH_3 is stronger base than PH_3 why?

State reason : BH_3 forms dimer.

Bond angle in H_(2)O is greater than that of H_(2)S - explain.
