Chapter 8, Problem 29P

Give the structure of the products that you would expect from the reaction of 1-butyne with:

(a) One molar equivalent of $B{r}_2$

(b) One molar equivalent of HBr

(c) Two molar equivalents of HBr

(d) $H_2$ (in excess)/Pt

(e) $H_2,N{i}_{2}B\left(P-2\right)$

(f) $NaN{H}_2$ in liquid $N{H}_3$, then $C{H}_{3}I$

(g) $NaN{H}_2$ in liquid $N{H}_3$, then ${\left(C{H}_3\right)}_{3}CBr$
