Dehydration of alcohols to form an alkene is always carried out with conc. H2SO4 and not with conc. HCl or HNO3. Explain.

(c) either metals or non-metals 

Correct answer is (D) always a non-zero number

Because it forms a dense fog of sulphuric acid which does not condense easily.

[Hint :  (a) (b) NaNO3 + H2SO4 =>NaHSO4 + HNO3]

X = NO2 Y = N2O

The formation of ethers by dehydration of alcohol is a bimolecular reaction (SN2) involving the attack of an alcohol molecule on a protonated alcohol molecule. In the method, the alkyl...

HCl, HNO3, etc., ionise in the aqueous solution to produce H+ ions. Hence, they show acidic character. Compounds like C2H5OH and glucose do not ionise in the aqueous solution to give...

 (c) C element is oxidised by conc. H2SO4 into two gaseous products 

CH2 = CH-CH2OH

Total no. of moles of CO  and CO2  = a + b + b = a + 2b Total no. of moles of CO2 = b Moles fraction of CO2 absorbed in KOH = b/a+...
