Question
The diatomic molecule that would contain the shortest & strongest covalent bond would be A) HBr B) HCl C) HF D) HI Based on electronegativity trends in the periodic table, the compound that would have the greatest% ionic character would be _____ A) CaO B) HCl C) LiBr D) KF The total number of resonance structures that could be drawn for the nitrite anion would be: A) 0 B) 1 C) 2 D) 3 The least polar type (not number) of covalent bonds would be found in the _____ molecule. A) H_2O B) OCl_2 C) SO_2 D) CO_2Explanation / Answer
1) option C - HF will have the shortest and strongest bond.
2) the more the electronegativity difference the more ionic nature of the bond
HCl ( Cl - 3.16, H -2.2) , CaO (Ca - 1.00, O - 3.44) , KF (K- 0.82, F - 3.98) , LiBr (Li - 0.98, Br- 2.96)
Option D - KF has more % ionic character as the ekectronegative difference is more than the rest of tge options.
3) nitrite ion has 2 resonance structures.
4) least polar type attributes to least electronegativity difference between the atoms forming the bond.
Electro negativity difference of the given componds
H2O - 1.24 , OCl2 - 0.28 , SO2-0.86, CO2- 0.89)
Option B - OCl2 is least polar
