Question

 22- In what condition a real gas behaves like ideal gas? 

a) High pressure, high temperature 

b) High pressure, low temperature 

c) low pressure, low temperature 

d) low pressure, high temperature 

23- Which of the following statements are true? 

a) σ bonds form from side to side overlap of atomic orbitals 

b) TT bonds form from side to side overlap of atomic orbitals 

c) σ bonds form from head to head overlap of atomic orbitals 

d) TT bonds form from head to head overlap of atomic orbitals 

e) Both b and c 

24. Which of the following molecules have resonance structures?  

Answer 1

22.

real gas can behave like an ideal gas under high temperature and low pressure because potential energy due to intermolecular forces becomes less signigicant as compared to kinetic energy of particle.

so option (d) is correct.

option (a), (c) and (b) are incorrect based on upper information.

23.as we know by defination,

sigma bonds are formed by head to head overlapping and pi bond is formed by sideway overlapping.

based on defination option (e) is correct.

other options are incorrect based on defination.
