Organic Chemistry-Design a Synthesis for 1-decanol

Using ethene and 1-octene, design a synthesis for 1-decanol. Hint: Try working on the two alkenes first before trying to make 1-decanol.

Need an answer, not "hints" for best answer.

Thanks!

CH3(CH2)5CH=CH2 == 1)B2H6 2)H2O2 ==> CH3(CH2)7-OH (Hydroboration)

CH3(CH2)7)-OH == PBr3 ==> CH3(CH2)7-Br

CH3(CH2)7-Br == Mg, ether ==> CH3(CH2)7-MgBr (Grignard reagent)

CH2=CH3 == m-Cl-C6H4CO3H ==> Ethylene oxide (Epoxidation with m-chloroperbenzoic acid)

CH3(CH2)7-MgBr + Ethylene oxide ===> CH3(CH2)9-OH (1-Decanol)
