Question 24

What is homolytic fission?

Answer 24

When a covalent bond breaks by homolytic fission each of the bonded atoms takes one of the shared elecrons from the bonds

Question 25

What is heterolytic fission?

Answer 25

When a covalent bond breaks by heterolytic fission, one of the bonded atoms takes both of the electrons from the bond

Question 26

Why do alkanes not react with most common reagents?

Answer 26

C-H and C-C bonds are strong C-C bonds are non polar The electronegativety of carbon and hyrogen is so similar that the C-H bond can be considered to be non-polar
