Bond length and strength

Question 1

what happens to the bond length when the number of bonds between carbon-carbon atoms increases

Answer 1

the bond length decreases

Question 2

what happens to the bond strength when the number of bonds between carbon-carbon atoms increases

Answer 2

the bond strength increases

Question 3

what happens to the bond length between carbon atoms from alkanes to benzene to alkenes.

Answer 3

the bond length between carbon atoms decreases from alkanes to benzene to alkenes

whilst bond strength increases

Question 4

is a sigma bond stronger than a pi bond

Answer 4

a sigma bond is stronger than a pi bond due to greater orbital overlap

Question 5

are pi and sigma bonds strong together compared to a sigma or pi bond alone

Answer 5

sigma and pi bonds together are stronger than either a sigma or pi bond alone
