b. K-Cl
c. C-I
d. C≡O
e. N≡N
Choose the bond below that is the weakest.
a. C=S
b. K-Cl
c. C-I
d. C≡O
e. N≡N
a. C=S (two covalent bonds are stronger)
b. K-Cl (ionic bond as electronegativity difference is high between both elements hence, strongest bond)
c. C-I (only one covalent bond and size difference is more between both atoms. hence, weakest bond)
d. C≡O (three covalent bonds are stronger)
e. N≡N (three covalent bonds between similar atoms are stronger)
