Question

Give chemical equation 1)2-methyl propene is irradiated with HBr in presence of benzoyl peroxide.
2)2-butene is heated with alkaline KMnO4​

Answer 1

Answer:

1. When two methyl propene is irradiated with HBr in the presence of benzoyl peroxide then according to Marconikows rule product will be 2 bromo 2 methyl propane:

Equation 1 see on image

Benzoyl peroxide is used in skin treatment. It help in reducing the amount of acne-causing bacteria and by causing the skin to dry.

2. When 2 butene is heated with hot alkaine KMnO4 then the product will be      2 molecules of ethanoic acid:

CH_{3} -CH=CH-CH_{3}     {Hot Alkaline KMnO_{4}/OH }_{----->}    2CH_{3} COOH[/tex]

Answer 2

1. When 2-Methyl propene is reacted with HBr in the presence of benzoyl peroxide, 1-Bromo-2-methyl propane is obtained as the major product. The reaction follows anti-Markonivov's rule because of the presence of peroxide molecule in the reaction.
2. When 2-butene is treated with alkaline KMnO₄, it undergoes oxidation reaction and the product obtained is an enantiomeric mixture of vicinal diol, i.e., ± 2,3-Dihydroxybutane.
