Chemistry 1 Marks Question

Alcohols are relatively more soluble in water than the corresponding hydrocarbons because alcohol molecules can form hydrogen bonds with water. Hydrocarbons do not form hydrogen bonds with water.

Phenols are more acidic then alcohols due to the formation of stable phenoxide ion and it also have resonance stabilisation but alcohols do not.

(i) 2-Methyl Propan-1-ol
(ii) Butane-1, 3 diol.

Phenol is more acidic than alcohols due to the stablisation of phenoxide ion trhough resonance. Phenoxide ion is more stable than alkoxide ion.

Diethyl ether does not react with sodium because hydrogen atom is not attached to the electronegative oxygen atom. In the absence of available hydrogen or other ionic species the sodium will not react with diethyl ether.

Alcohols are more soluble in water because they make hydrogen bond with water as compared to same molecular weight hydrocarbon.

Alcohol has intermolecular bonding present in thus its aqueous solution have no ion present in it.
Due to absence of ions its aqueous solution is bad conductor of electricity.

Grignard reagent forms complex with ether but not with benzene because ether has lone pair of electrons while benzene does not have lone pair of electrons to form coordinate complex.

Due to larger size of alkyl groups, the oxygen atom in ethers does not form intermolecular H-bonding with water.

o-methoxyphenoxide ion left after the loss of a proton is destabilized by resonance. But o-nitphenoxide ion is stabilized by resonance thereby making o-nitrophenol stronger acid.
