when structure of any compound is given then for predicting hybridisation we simply calculate number of sigma bond and say hybridisation (eg.3=sp2 5=sp3d 6-sp3d2 ) cant it be that s and d are getting hybridised and p remains unhybridised ?        Also  since s can not form pi bond whatever 1 bond formed has to be sigma and from s so is it that paired electron of s orbital must get unpaired even for molecules like O2 and its sp ???

Please explain in detail why option (b) is not the answer, since I F charge is the charge required to deposit 1 equivalent of a substance.& 1F is also the charge on one mole of electrons, so option (b)should be the answer but according to answer key it is option (a)?


The number of electrons required to deposit 1 gm equivalent aluminium (at. wt. = 27) from a solution of aluminium chloride will be 
(A)  3           (B) 1                      (C)  4                    (D)  2
