NEET Questions / Chemistry / Chemical Bonding and Molecular Structure / Bond Parameters
Which of the following statements regarding bond parameters is INCORRECT?
A higher bond order usually implies a stronger bond.
A shorter bond length usually corresponds to a stronger bond.
Higher bond energy means a stronger bond.
A longer bond length implies greater bond strength.
Consider the isoelectronic species , , and . Arrange them in increasing order of bond length.
Nโ < CO < CNโป
CNโป < CO < Nโ
CO < Nโ < CNโป
Nโ < CNโป < CO
Which factor does NOT contribute significantly to the difference in bond lengths between single, double, and triple bonds?
Bond Order
Atomic Size
Bond Strength
Electronegativity differences
The bond length in is experimentally determined to be 121 pm. Using this information and the concept of bond order, predict the approximate bond length in (superoxide ion).
Slightly greater than 121 pm
Slightly less than 121 pm
Approximately equal to 121 pm
Significantly greater than 121 pm
The percentage ionic character of a bond is determined to be 18%. If the observed dipole moment is 1.2 D, what is the theoretical dipole moment assuming 100% ionic character (given: 1 D = C m)?
0.22 D
2.16 D
6.7 D
18 D
Which of the following is NOT a bond parameter?
Bond length
Bond angle
Bond enthalpy
Electronegativity
Bond length is the distance between the nuclei of two bonded atoms. It is usually expressed in:
Joules
Kilograms
Angstroms
Degrees
As the bond order between two atoms increases, the bond length generally:
Increases
Decreases
Remains the same
Becomes zero
