Answer: between 45% and 70%
Step-by-step explanation:
taking this step by step, let us analyze this question carefully.
From the original image in the question, as can be seen in the second uploaded image, we observe that;
potassium hydroxide having being less bulky produces about 45% of 2-methyl-butane whereas potassium tert-butoxide having being bulky produces 70% of this product.
Given the potassium propoxide as the base and intermediate to that of potassium hydroxide and potassium tert-butoxide, it produces 2-methyl-1-butane in between 45% to 70%.
Cheers i hope this helped!!!!
