Compound : No. of
valance electron on the central atom
XeF2 : 10
AlCl3 : 6
SF6 : 12
SCl2 : 8
1F = 96500 C = 1 mole of e− = 6.023 ×1023
e−
∴ 9650 C = [ 6.22 ×1023 / 96500 ] × 9650 = 6.022×1022
= 6.022×1022
The incorrect statement is option
(b)
Physisorption is an exothermic
process. Hence increase in temperature decreases the physisorption.
In the hydrocarbon
state of hybridisation of carbon 1,2,3,4 and 7 are in the
following sequence.
