Identify the appropriate reagents from the table to accomplish steps a-h. Select the reagents in the order that they are to be used; i.e. 382 means that step 'a' is PCC, step 'b' is NaNH2, and step 'c' is Br2, H2O.
The reagents are a = 1 , b = 2 , c= 3 , d= 1 , e = 7, f= 8, g = 8 and h = 5
a is used for eleimination to give alkene thus is t- butoxide
b used for addition of HObr, thus Br2/H2O
C used tooxidise OH to ketone, so it is PCC
d is again elimination by t- butoxide
f is elimination of two HBr to give alkyne , hence 2 equivalents of NaNH2
g is to get alkynide ion by using one equivalent of NaNH2
h is reaction of alkynide with a ketone followed by acidification to give a tertiary alcohol, thus h is H3O+
