Short Answer

Expert verified

Answer

Step by step solution

01

Resonance structures

The resonance hybrid, which is the contributing structure of several structures, are indicated at the end while noting down the resonance structure of a particular compound.

02

Butylated hydroxyl anisole(BHA)

Butylated hydroxyl anisole comprises a combination of two isomeric alcohols. They are obtained from the compounds 4-methoxyphenol and isobutylene.

03

 Step 3: Resonance structures of the radical that results from the abstraction of hydrogen atom from the antioxidant BHA

Resonance structures are a way of describing the electron delocalization in a particular molecule. The resonance structures that result from the abstraction of the hydrogen atom from the antioxidant BHA can be given as:

Question: In the presence of a radical initiator (Z* ), tributyltin hydride ( R3SnH,R=CH3CH2CH2CH2 ) reduces alkyl halides to alkanes: R'X+R3SnH→R'H+R3SnX. The mechanism consists of a radical chain process with an intermediate tin radical:

This reaction has been employed in many radical cyclization reactions. Draw a stepwise mechanism for the following reaction.

Question:What reagents are needed to convert cyclopentene into

(a)bromocyclopentane;

(b) trans-1,2-dibromocyclopentane;

(c) 3-bromocyclopentene?

Question: a. What product(s) (excluding stereoisomers) are formed when Y is heated with Cl2 ?

b. What product(s) (excluding stereoisomers) are formed when Y is heated with Br2?

c. What steps are needed to convert Y to the alkene Z?

Question: Five isomeric alkanes (A–E) having the molecular formula C6H14 are each treated with Cl2 + hv to give alkyl halides having molecular formula C6H13Cl . A yields five constitutional isomers. B yields four constitutional isomers. C yields two constitutional isomers. D yields three constitutional isomers, two of which possess stereo-genic centres. E yields three constitutional isomers, only one of which possesses a stereo-genic centre. Identify the structures of A–E.

Questions: Rank the indicated hydrogen atoms in order of increasing ease of abstraction in a radical halogenation reaction.
