Alcohols, Phenols and Ethers
The intermediate X, in the reaction :

In the following reaction :

The compounds A and B respectively are :
Hex-4-ene-2-ol on treatment with PCC gives 'A'. 'A' on reaction with sodium hypoiodite gives 'B', which on further heating with soda lime gives 'C'. The compound 'C' is :
In the following reaction

The $\%$ yield for reaction I is $60 \%$ and that of reaction II is $50 \%$. The overall yield of the complete reaction is __________ $\%$. [nearest integer]
Explanation:

Let initial moles of reactant taken = n
Total moles obtained for benzene sulphonic acid (with % yield = 60%) = 0.6n

Moles of benzene sulphonic acid before reaction II = 0.6n
Moles obtained for phenol (with % yield = 50%) = 0.6 × 0.5n = 0.3n
So over all % yield of complete reaction $=\frac{0.3 \mathrm{n}}{\mathrm{n}} \times 100=30$
The number of chiral alcohol(s) with molecular formula C4H10O is ________.
Explanation:

Out of which only two are chiral
In the given reaction,

the number of sp2 hybridised carbon(s) in compound 'X' is ________.
Explanation:
Compound 'P' on nitration with dil. HNO3 yields two isomers (A) and (B). These isomers can be separated by steam distillation. Isomers (A) and (B) show the intramolecular and intermolecular hydrogen bonding respectively. Compound (P) on reaction with conc. HNO3 yields a yellow compound 'C', a strong acid. The number of oxygen atoms is present in compound 'C' _____________.
Explanation:

Assertion (A) : Treatment of bromine water with propene yields 1-bromopropan-2-ol.

Statement II : o-Nitrophenol has high melting due to hydrogen bonding.
In the light of the above statements, choose the most appropriate answer from the options given below :

B reacts with Hydroxyl amine but does not give Tollen's test. Identify A and B.
Explanation:
2 moles of CH3MgBr reagent will be used. Chemical reaction is as follows
The product 'P' gives positive ceric ammonium nitrate test. This is because of the presence of which of these –OH group(s)?
methanol, phenol, p-ethoxyphenol
(Atomic mass : C = 12; H = 1; O = 16)
Explanation:
mass of Salicylaldehyde = 12 × 7 + 6 × 1 + 16 × 2 = 122
mass of carbon = 12 × 7 = 84
$ \therefore $ mass % of C in P = ${{84} \over {122}}$ $ \times $ 100
= 68.85 % $ \simeq $ 69 %
Explanation:
So, the possible structures which are optically active and have phenolic group are as followed :

Therefore, total optically active isomers will be 6.
