a) Interpretation: How to carry out the conversion shown is to be stated. Concept introduction: Terminal alkenes can be converted in to aldehydes with same number of carbon atoms by hydroboration-oxidation reaction. The addition of water occurs with syn stereochemistry following anti-Markovnikov stereochemistry to yield an alcohol. The alcohol upon oxidation yields an aldehyde. To state: How to carry out the conversion shown.

Question

Rank (1-4) from most reactive to least reactive (in decreasing reactivity in an elimination reaction with NaOH in DMF at 100 degrees celsius)

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation:

How to carry out the conversion shown is to be stated.

Concept introduction:

The alkene is converted in to a dibromo derivative by treating with Br₂ in the presence of CH₂Cl₂. The dibromo derivative is then treated with two equivalents of KOH when dehydrohalogenation takes place yield a terminal alkyne. The terminal alkyne is then converted in to its sodium salt. The sodium alkynide when treated with CH₃Br yields the next higher alkyne which when reduced by Li in liq.NH₃ produces the trans alkene.

To state:

How to carry out the conversion shown.
