The reaction of 
with HBr gives (1998 - 2 Marks)
with HBr gives (1998 - 2 Marks)The mechanism of this reaction is represented as follows.
The ether 
when treated with HI produces (1999 - 3 Marks)
when treated with HI produces (1999 - 3 Marks)TIPS/Formulae :
The aromatic ethers are cleaved to give phenol as one of the products.
In the reaction 
the intermediate (s) is (are) (2010)
the intermediate (s) is (are) (2010)
Product of reaction of phenol with NaOH/Br2 is sodium salt of 2,4,6-tribromophenol. Hence, species (I), (II), (III) are formed as intermediate.
The major product(s) of the following reaction is(are) (JEE Adv. 2013)
The correct combination of names for isomeric alcohols with molecular formula C4H10O is/are (JEE Adv. 2014)
Isomeric alcohols with molecular formula C4H10O
The reactivity of compound Z with different halogens under appropriate conditions is given below: (JEE Adv. 2014)
The observed pattern of electrophilic substitution can be explained by
—OH group is strongly activating and o, p-directing due to +M effect. Thus positions a, b and c are the sites for attack by an electrophile. However, sites b and c are not preferred by bulky electrophile due to steric crowding. Thus more bulky electrophile (like I2) can attack only site a, which is least sterically hindered, a bit smaller electrophile (Br2) can attack at sites a and also b (relatively less sterically hindered site) and the smallest electrophile (Cl2) can attack all the three sites, viz., a, b and c (most sterically hindered site).
The major product U in the following reactions is
