Chapter 11, Problem 11.56P

Devise a synthesis of each compound using ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_2\text{OH}$ as the only organic starting material (a) ${\text{CH}}_{\text{3}}\text{C}\equiv {\text{CCH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_3$; (b) ${\text{CH}}_{\text{3}}\text{C}\equiv {\text{CCH}}_{\text{2}}\text{CH}\left(\text{OH}\right){\text{CH}}_3$. You may use any other needed reagents.
