When 3 Phenylpropene reacts with HBr in the presence of peroxide The major product is?
In this type of reaction, Markownikoff’s rule is applicable. But, by Markownikoff’s addition rule the major product will be 1-Bromo-1-phenylethane.
Which of the following will be the major product when 3 Phenylpropene reacts with HBr?
3-phenyl propene on reaction with HBr undergoes hydrohalogenation reaction to form 1-bromo-1-phenyl benzene.
What is the structure of 1 Phenylpropene?

What would be the product when 2 pentene reacts with HBr?
Accordingly, if hydrogen bromide (or other unsymmetrical reagent) is added to 2-pentene, the reaction would follow to give 2-bromopentane as the predominant product.
How many bonds are there in 1 phenyl propene?
Therefore, there are 8 sigma bonds and 1 pi bond.
What happens when pentene reacts with HBr?
What is the action of HBr on pentene?
Because the HBr adds on the “wrong way around ” in the presence of organic peroxides, this is often known as the peroxide effect or anti-Markovnikov addition. In the absence of peroxides, hydrogen bromide adds to propene via an electrophilic addition mechanism. That gives the product predicted by Markovnikov’s Rule.
How many pi bonds are present in phenol?
The phenol which has molecular formula C6H5OH.has totally 13 sigma bonds and 3 pi bonds.
How many sigma Σ bonds and pi π are there in Cyclopropene?
There are two compunds with this molecular formula, cyclopropane and propene (or propylene), considered to be structural isomers. Notice that cyclopropane has a total of 9 sigma bonds, each of these bonds having 2 shared electrons.
What is the function of phenyl?
Phenyl groups tend to resist oxidation and reduction. Phenyl groups (like all aromatic compounds) have enhanced stability in comparison to equivalent bonding in aliphatic (non-aromatic) groups. This increased stability is due to the unique properties of aromatic molecular orbitals.
