If the given four electronic configurations,
(i) n = 4, l = 1
(ii) n = 4, l = 0
(iii) n = 3, l = 2
(iv) n = 3, l = 1
are arranged in order of increasing energy, then the order will be
(iv) < (ii) < (iii) < (i)
(ii) < (iv) < (i) < (iii)
(i) < (iii) < (ii) < (iv)
(iii) < (i) < (iv) < (ii)

Dissolving NaCN in de-ionised water will result in a solution having
pH < 7
pH = 7
pOH = 7
pH > 7
Among Me3N, C5H5N and MeCN (Me = methyl group) the electronegativity of N is in the order
MeCN > C5H5N > Me3N
C5H5N > Me3N > MeCN
Me3N > MeCN > C5H5N
Electronegativity same in all
The shape of XeF will be
square pyramid
trigonal bipyramidal
planar
pentagonal bipyramid
C.
planar
Xe show sp3d3 hybridisation in XeF. Thus, its geometry is pentagonal bipyrimidal.
But, number of electron pair = = 7
Number of bond pair = 52; Number of lone pair = 2
A lot of electrons are present at axil poisition and all bonds are in same plane. Hence, the shape is planar.
