Solution
Verified by Toppr
Correct option is D. $$(a)- (iii), \ (b)- (i), \ (c)- (ii), \ (d)- (iv)$$
a) Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide.
b) Temporary hardness is a type of water hardness caused by the presence of dissolved bicarbonate minerals (calcium bicarbonate and magnesium bicarbonate).
c) $$B_2H_6$$ - Electron deficient hydride
d) $$H_2O_2$$ - Hydrogen peroxide is a nonplanar molecule with (twisted) symmetry. It is non–linear, non–planar molecule with a open book structure.
Option D is correct.
b) Temporary hardness is a type of water hardness caused by the presence of dissolved bicarbonate minerals (calcium bicarbonate and magnesium bicarbonate).
d) $$H_2O_2$$ - Hydrogen peroxide is a nonplanar molecule with (twisted) symmetry. It is non–linear, non–planar molecule with a open book structure.
