A. Methanol is also known as 'wood spirit' as it was produced by the destructive distillation of wood.
B. In Kolbe's reaction, 2 - hydroxy benzoic acid (salicylic acid) is prepared by the reaction of phenol with $\mathrm{CO}_2$ gas.
C. Williamson synthesis is an important method for the preparation of ethers. In this method, an alkyl halide is allowed to react with sodium alkoxide.
$$R-X+R-\mathrm{ONa} \longrightarrow \mathrm{ROR}+\mathrm{NaX}$$
D. When a $2^{\circ}$ alcohol is allowed to pass over heated copper at 573 K , dehydrogenation takes place and an ketone is formed.
E. On treating phenol with chloroform in the presence of NaOH , an aldehydic group is introduced at ortho position of benzene ring
F. Ethanol is prepared by the fermentation of sugars.

Assertion (A) Addition reaction of water to but-1-ene in acidic medium yields butan-1-ol.
Reason (R) Addition of water in acidic medium proceeds through the formation of primary carbocation.
Assertion (A) p-nitrophenol is more acidic than phenol.
Reason (R) Nitro group helps in the stabilisation of the phenoxide ion by dispersal of negative charge due to resonance.
Assertion (A) IUPAC name of the compound
is 2-ethoxy-2-methylethane
Reason (R) In IUPAC nomenclature, ether is regarded as hydrocarbon derivative in which a hydrogen atom is replaced by - OR or - OAr group [where, $\mathrm{R}=$ alkyl group and $\mathrm{Ar}=$ aryl group].
Assertion (A) Bond angle in ethers is slightly less than the tetrahedral angle.
Reason (R) There is a repulsion between the two bulky $(-R)$ groups.
