MCQ (Single Correct Answer)

-1

Four diatomic species are listed below. Identify the correct order in which the bond order is increasing in them

$$NO < {O_2}^ - < {C_2}^{2 - } < He_2^ + $$

$${O_2}^ - < NO < {C_2}^{2 - } < He_2^ + $$

$${C_2}^{2 - } < He_2^ + < {O_2}^ - < NO$$

$$He_2^ + < {O_2}^ - < NO < {C_2}^{2 - }$$

MCQ (Single Correct Answer)

-1

The electronegativity difference berween N and F is greater than that between N and H yet the dipole moment of NH₃ (1.5D) is larger than that of NF₃ (0.2 D). This is because

in NH₃ the atomic dipole and bond dipole are in the opposite directions whereas in NF₃ these are in the same direction

in NH₃ as well as in NF₃ the atomic dipole and bond dipole are in the same direction

in NH₃ the atomic dipole and bond dipole are in the same direction whereas in NF₃ these are in opposite directions

in NH₃ as well as in NF₃ the atomic dipole and bond dipole are in opposite directions.
