25.10 Bond Length

Question 1

BDE

Answer 1

bond dissociation energy: energy required to break bond homolytically

Question 2

homolytic bond cleavage

Answer 2

one electron of the bond goes to each molecule fragment (forms 2 radicals)

Question 3

heterolytic bond cleavage

Answer 3

both electrons of the bond goes to the same atom (forms an anion and a cation)

Question 4

what happens when you increase bond order?

Answer 4

for SIMILAR bonds only

↑ BO = ↓ bond length = ↑ strength

Question 5

what happens when you increase s or p character of a bond?

Answer 5

increase s character = shorter bond length = increase strength
increase p character = longer bond length = decrease strength
