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
B.
sp3-hybridisation and distorted tetrahedral geometry
(i) Hybridisation = 1/2[no. of e- in valence shell of central atom + no. of monovalent atoms + charge on anion - charge on cation].
(ii) Shape or geometry of molecule depends on lone pair and bond pair of electrons present in it.
Hybridisation of N in NH3 = 1/2 (5+3+0-0) = 4
∴ sp3 3 hybridisation.
It has 3 bond pair and 1 lone pair of electrons, so it has distorted tetrahedron shape.
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
