Chapter 6: Q60P (page 283)

What reagents are needed to synthesize the following alcohols?

Short Answer

Expert verified

Here we have to find What reagents are needed to synthesize the following alcohols:

Step by step solution

01

What is electrophile and nucleophile

Electreophile= The electron loving compound is called electrophile. It may have positive charge on it.

Nucleophile= The nucleus loving compound is called nucleophile. It may have negative charge on it.

02

How the reaction proceed

Markoniv addition=Positive ion will go to that double bonded carbon which has more no of hydrogens attached and negative ion will go towards that carbon which has less number of hydrogens attached.

In hydroboration oxidation reaction anti markoniv addition takes place.

03

Final answer

When OH is on second carbon then H2O and H2SO4 is used. Markoniv addition takes place but due to methyl shift to form stable carbocation theOH is on second carbon.

When hydroboration oxidation takes place then anti markoniv addition takes place.
