Question

Which bond in each of the following pairs of bonds is the strongest?

a) CC or C = C
b) C-N or C = N
c) CO or C = 0
d) H-F or H - Cl
e) C-H or O - H
f) C-N or C-0

Answer 1

The strongest bond is determined by the bond type and electronegativities of the atoms involved. Bond strength increases as the bond type changes from single bond to double bond to triple bond.

Step-by-step explanation:

In each pair of bonds, the strongest bond is determined by the bond type and the electronegativities of the atoms involved. The bond strength increases as the bond type changes from single bond, double bond, to triple bond.

a) In the pair CC or C = C, the strongest bond is C = C because it is a double bond.

b) In the pair C-N or C = N, the strongest bond is C = N because it is a triple bond.

c) In the pair CO or C = O, the strongest bond is C = O because it is a double bond.

d) In the pair H-F or H-Cl, the strongest bond is H-F because fluorine (F) is more electronegative than chlorine (Cl).

e) In the pair C-H or O-H, the strongest bond is O-H because oxygen (O) is more electronegative than carbon (C).

f) In the pair C-N or C-O, the strongest bond is C-O because it is a double bond.
