3 recent questions with answers. The full set of 58 is free to practise.

1. NEET 2023EasyIntermolecular Forces
   Q1

   Intermolecular forces are forces of attraction and repulsion between interacting particles that will include : A. dipole - dipole forces B. dipole - induced dipole forces C. hydrogen bonding D. covalent bonding E. dispersion forces

   • AA, B, C, D are correct
   • BA, B, C, E are correct
   • CA, C, D, E are correct
   • DB, C, D, E are correct

   Show answer & solution

   Correct answer: (B)

   Intermolecular forces are the forces of attraction and repulsion between interacting molecules. This term does not include covalent bonds as covalent bond holds atoms of a molecule together.
   
   Hence, dipole - dipole forces, dipole - induced dipole forces, hydrogen bonding and dispersion forces are intermolecular forces.
2. NEET 2023MediumDeviation from Ideal Gas
   Q2

   The correct van der Waals equation for 1 mole of a real gas is :

   • A$\left(p+\frac{a}{V^2}\right)(V-b)=RT$
   • B$\left(p+\frac{V^2}{a}\right)(V-b)=RT$
   • C$\left(p+\frac{{an}^2}{V^2}\right)\left(V^2-nb\right)=RT$
   • D$\left(p+\frac{{an}^2}{V}\right)(V-nb)=nRT$

   Show answer & solution

   Correct answer: (A)

   $$\left(P+\frac{a}{V^2}\right)(V-b)=RT$$
3. NEET 2023MediumIdeal Gas Equation
   Q3

   The correct option in which the density of argon (Atomic mass $=40$ ) is highest :
   [NEET 2023 mpr ]

   • ASTP
   • B$0^{\circ }C$, 2atm
   • C$0^{\circ }C$, 4 atm
   • D$273^{\circ }C,4atm$

   Show answer & solution

   Correct answer: (C)

   $$\rho =PM/RT$$For maximum density, pressure should be maximum and temperature should be minimum.
