1) Hydroboration oxidation give least substituted alcohol from Alkene.
2) Dehydration of alcohol with acid give Alkene.
3) Dehydration give Alkene but in this case there is 1,2-hydride shift which give final product.
4) formaldehyde give primary alcohol with grignard reagent.
5) Ketone give tertiary alcohol with grignard reagent.
