Answer:
Correct option : B
Explanation:
First compare with
there are two lone pair in but only one lone pair presen in the
so more lone pair means more repulsion and hence less bond bond angle beacuse of lone pair repulsion bonded atom come closer and hence bond angle decreased .
bond angle inversely proporional to repulsion so more repulsion means less bond angle
does no exist it exist only in the form of
and here assuming
because in case of
difficult to compare bond angle because here two different type of bond angle is present.
there is no lone pair in the so here will no be any repulsion and hence bond will be more in
as compared to
The concentration of the FeSO4 solution in molarity would be 0.4356
The concentration can be derived first by writing out the balanced equation of the reaction:
From the balanced equation: for every 1 mole of KMnO4, 5 moles of FeSO4 is needed for complete oxidation.
Recall that: mole = molarity x volume
Mole of KMnO4 needed = 0.1327 x 0.01642
= 0.002179 mole
1 mole KMnO4 = 5 mole FeSO4
0.002178 mole = 5 x 0.002178/1
= 0.01089 moles of FeSO4
Molarity of FeSO4 = mole/volume
= 0.01089/0.025
= 0.4356 M
