Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion : tert-Butyl methyl ether reacts with \(HBr\) to form fert-butyl bromide and methanol. 

Reason : It follows \(S_N1\) mechanism.

In the light of the above statements, choose the correct answer from the options given below

Major product of the given reaction is
bond angle is less than the normal tetrahedral bond angle. Lone pair-lone pair repulsion decreases bond angle.
$ { ->[{(HI (excess)}][{\Delta}] }$
But-1-ene $ { ->[{(CH_3COO)_2Hg}][{H_3O^+}] }$ ? The product in the above reaction is
Phenol is more reactive than benzene towards electrophilic substitution reaction. In the case of phenol, the intermediate carbocation is more resonance stabilised.
The correct increasing order of reactivity for the following molecules towards electrophilic aromatic substitution is
The correct decreasing order of $pK_a$ is
$ {A (C10H_18O) ->[{HCL}] P}$
Degree of unsaturation of $A = 2$, it contains no double or triple bonds.
In Oppenauer's oxidation,
Oxidation product of 1,2-cyclopentanediol with $HIO _{4}$ gives
When phenol reacts with phthalic anhydride in presence of $H _{2} SO _{4}$ and heated and hot reaction mixture is poured in $NaOH$ solution, then product formed is
Propene on hydroboration and oxidation produces
$CH _{3} OC _{2} H _{5}$ and $\left( CH _{3}\right)_{3} C - OCH _{3}$ are treated with hydroiodic acid. The fragments after reactions obtained are
Isopropyl benzene on air oxidation in the presence of dilute acid gives
The $pK_a$ of acetic acid is lower than that of phenol. Phenoxide ion is more resonance stabilised.
The major products formed by heating $C_6H_5CH_2OCH_3$ with $HI$ are $C_6H_5CH_2I \, and \, CH_ 3OH. $ Benzyl cation is more stable than methyl cation
Intermolecular hydrogen bonding is strongest in
Lucas test is used for the determination of
Phenol is a weaker acid than ethanol. Groups with $+M$ effect and $-I$ effect decrease acidity at $m$-position.
Which of the following statements is not true about alcohols?
o-Nitrophenol is more volatile than p-nitrophenol Intramolecular hydrogen bonding is present in o-nitrophenol while intermolecular H bonding is in p-nitrophenol.
In the reaction: Phenol $ { ->[{NaOH}][{CHCl_3}] }$ $A$ $ { ->[{H^+}][{}] }$ $B, B$ is identified as
