Geometry of ammonia molecule and the hybridisation of nitrogen involved in it are
sp3-hybridisation and tetrahedral geometry
sp3-hybridisation and distorted tetrahedral geometry
sp2-hybridisation and triangular geometry
None of the above
Number of electrons in the valence orbit of nitrogen in an ammonia molecule is
8
5
6
7
A.
8
Count total electrons in valence shell of nitrogen and hydrogen.
∴ total electron in NH3= 5+ 1+1+1= 8
Be in BeCl2 undergoes
diagonal hybridisation
trigonal hybridisation
tetrahedral hybridisation
no hybridisation
Enthalpy (H) is equal to
internal energy (E)
product of pressure (p) and volume (V) of gas
internal energy (E)+ pV
work (W) done by a system
0.5 M ammonium benzoate is hydrolysed to 0.25 percent, hence, its hydrolysis constant is
2.5 x 10-5
1.5 x 10-4
3.125 x 10-6
6.25 x 10-6
