- How many mono-chlorinated products of 2-methyl butane will be formed upon chlorination in the presence of sunlight?
- Find the percentage of major product formed.
Six products were formed: two pairs of enantiomers and two achiral chloroalkanes.
Until here my answer was correct, confirmed by my teacher.
For the second part that is the percentage yield I had an issue with the enantiomers. I calculated the relative yield ratios by multiplying probability factor and rate factor.
For cases A and B, where enantiomers are being formed, I further multiplied $p_\mathrm{f} \times r_\mathrm{f}$ by half since there's an equal likelihood of each of the enantiomers to form. My teacher said this is wrong, as we do not multiply it by half.
So, my question is why?
