Question

In the following reactions I. CH3 CH CH CH3 CH3 OH H+/ A + B Major Minor II.   HBr dark, major minor absenceof peroxide A C D the major products A and C are respectively

Answer 1

Answer:

Explanation:

when H+ is added, we need to give it to OH group and it will form H3O+ which is removed in further step

Which will create double bond

• forms 2 products

When major product is treated with HBr, Electrophilic addition takes place and major product is the one which follows saytseff rule

• that is the 3⁰ carbocation will be more stable hence Br will attack there

Answer 2

Answer: 1)  A- 2-methyl but-2-ene (major)         B-2-methyl butene(minor)

2) C- 2-bromo-2-methyl butane (major)    D- 1-bromo -2-methyl butane

absence of peroxide- markovnikoff addition
