Question

Arrange the following in the order of property indicated for each set:

(i) H2O, NH3, HCl, H2 (increasing magnitude of intermolecular forces)

(ii) O2, H2, He,N2 (ease of liquefaction)(Given critical temperature in K: 154.3, 33.2, 5.3, 126

respectively)

(iii) O2, He, CO2, CH4 (increasing value of van der Waal constant ‘a



please give the correct answer otherwise your answer will be reported❤❤❤❤​

Answer 1

Answer:

2:Order of liquefaction of gases h2 He o2 n2

hope it helps you

I know only one

mark as brainest answer

Answer 2

Answer:

(i) H2<HCl<NH3<H2O

(ii) He<H2<N2<O2

Explanation: In 1st H2 is dipole, HCl is dipole dipole, and Nh3 and H20 are Hydrogen bonds.

In 2nd greater the critical temperature easily a gas is liquefiable.

Sorry for 3rd one I didn't know it.
