Match the following and identify the correct option.
Column I
- A. $CO(g)+H_2(g)$
- B. Temporary hardness of water
- C. $B_2H_6$
- D. $H_2O_2$
Column II
- I. $Mg(HCO_3)_2+Ca(HCO_3)_2$
- II. An electron deficient hydride
- III. Synthesis gas
- IV. Non-planar structure
Correct answer: A → III, B → I, C → II, D → IV
Detailed Solution
$CO(g) + H_2(g)$ – water gas / synthesis gas
Temporary hardness of water – due to $Mg(HCO_3)_2$ and $Ca(HCO_3)_2$
$B_2H_6$ – an electron deficient hydride
$H_2O_2$ – non-planar, open book-like structure
Correct match: A-III, B-I, C-II, D-IV.
