bond legnth

Question 1

what is the definition of bond energy?

Answer 1

the energy required to break one mole of a particular covalent bond in the
gaseous state.

Question 2

what is the definition of bond legnth?

Answer 2

the internuclear distance of two covalently bonded atoms

Question 3

what affects bond length? (2)

Answer 3

1. size atom/ radius
   (big atom= large bond)
2. no. pi bonds
   (single bonds = greater bond length
   pi bonds = shorter bond legnths)

Question 4

How does bond length affect the bond energy?

Answer 4

Greater bond length= weaker bond energy
