Answer: 1. (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)

(a) \(\mathrm{CO+H_2}\) is water gas, called synthesis gas: (iii).
(b) Temporary hardness is due to \(\mathrm{Mg(HCO_3)_2}\) and \(\mathrm{Ca(HCO_3)_2}\): (i).
(c) \(\mathrm{B_2H_6}\) is an electron-deficient hydride: (ii).
(d) \(\mathrm{H_2O_2}\) has an open-book, non-planar structure: (iv).

So (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv), option (1).
