Alcohol Phenol And Ethers

Ortho product has intramolecular H- bonding & para product has intermolecular H- bonding. Thus it can be separated by steam distillation due to difference in B.

First reaction is EAS which will be given by that phenol derivative whose p-position is free for EAS reaction.

Trans product is more stable than Cis. ( Trans product feel less repulsion due to opposite direction)

Ease of Carbocation formation

Formation of Conjugated diene in option 3 make the given reactant most reactive towards dehydration in acidic conditions.

Fe? O? + CO → 2FeO + CO?

The above reaction takes place at 500 – 800 K in blast furnace.

Pumice stone is an example of solid sol. In this type of colloid, the dispersion medium is solid and the dispersion phase is gas.

H? O < H? S < H? Se < H? Te
Down the group acidic strength increases
So pK? value decreases

R: CH? OH
Certain mild reducing agents like hypophosphorus acid or ethanol reduce diazonium salts to arene and themselves get oxidised to phosphorous acid and ethanal respectively.

The IUPAC name giving the lowest number to the functional group obeying the lowest set of locants is 1-bromo-5-chloro-4-methylhexan-3-ol.
