Respuesta :
A) N-F becasue F ismore electronegative so the covalent bond is stronger
B) B-Cl because Cl is a smaller atom than Br so the covalent bond is stronger
C) O-F because the atoms are more electronegative so the bond is stronger.
D) C=O because the double bond is stronger than the single bond.
E) P-Cl because Cl is smaller than Br so the electrostatic force of attraction between the positive nucleus and the bonding electrons is stronger, thus the covalent bond is stronger
B) B-Cl because Cl is a smaller atom than Br so the covalent bond is stronger
C) O-F because the atoms are more electronegative so the bond is stronger.
D) C=O because the double bond is stronger than the single bond.
E) P-Cl because Cl is smaller than Br so the electrostatic force of attraction between the positive nucleus and the bonding electrons is stronger, thus the covalent bond is stronger
Answer:
A) N-F, B) B-F, C) O-F, D) C=O, E) P-Cl.
Explanation:
Bond energy is the energy that is to break the molecule apart. Bond energy affected by the electronegativity and no. of bonds.
A) N-F bond is more powerful than N-O because Fluorine is the highest electronegative element in the periodic table.
B) B-F has strongest bond than B-Cl, due to higher electronegativity of fluorine.
C) O-F has highest bond energy than B-C, because O is strong covalently bonded with fluorine which is the highest electronegative.
D) C=O has highest bond energy, because double bond has required more energy to break than the single bond.
E) P-Cl has high bond energy than the P-Br, because Cl has small size and more electronegative than Br.
