Question

Which one of the following substances will have both dispersion forces and dipole-dipole forces? H_2 CO_2 HCl BCl_3 Br_2 Which one of the following substances to have the lowest melting point?. Brl CsI LiI Nal Rbl Which one of the following is a buffer solution? 0.40M HCN and 0.10 KCN 1.0 M HNO_3 and 1.0 M NaNO_3 0.20 M CH_3COOH 0.10 M KCN For the overall chemical reaction shown below, which one of the following statements can be rightly assumed? 2H_2S(g) + O_2(g) rightarrow 2S(s) + 2H_2O(I) The rate law is, rate = k[H_2S]^2[O_2]. The rate law cannot be determined from the information given. The reaction is second-order overall. The reaction is third-order overall. The rate law is, rate = k[H_2S] [O_2]. Which of the following solutions is basic? [OH^-] = 1.0 times 10^-7 M [OH^-] 1.0 times 10^-7 M [OH^-] = 1.0 times 10^-10 M A first-order chemical reaction is observed to have a rate constant of 37 min^-1. What is the corresponding half-life for the reaction? 1.1 min 529 s 1.6 s 53 min 1.1 s

Explanation / Answer

22) Option c = HCL

Though all molecules have dispersion forces. But in the above options only HCl has dipole - dipole forces.

So the answer is HCL.
