(i) 3 - cyanobutanoic acid
(ii) 2 - methyl propanenitrile
(iii) phenyl carbylamine

Esters of an alcohol can react with another alcohol in the presence of a mineral acid to give the ester of second alcohol. The interchange of alcohol portions of the esters is termed trans esterification.

Sodium bi carbonate makes the stomach alkaline and thus more HCI is released which causes ulcer. Whereas Ranitidine prevent the interaction of histamine in the stomach wall and thus reduces the amount of HCI release

(i) Disaccharides linked through C₁ of the first to C₄ or C₆ of the second component are called reducing sugar. Eg: Lactose.
(ii) Disaccharides linked through the glycosidic carbon atoms of each component C₁ of glucose to C₂ of fructose are nonreducing disaccharides. Eg: Sucrose

A colloidal solution of gas is not possible as gases are completely miscible and always they form true solutions.

Lead storage battery.

Test to differentiate alcohol and phenols:
(i) Phenol react with benzene diazonium chloride to form a red orange dye, but ethanol has no reaction with it.
(ii) Phenol gives purple colouration with neutral ferric chloride solution, alcohols do not give such coloration with FeCI₃.
(iii) Phenol reacts with NaOH to give sodium phenoxide. Ethyl alcohol does not react with NaOH.

A plot of log k against  \(\frac { 1 }{ T } \) values gives a straight line with slope value equal to - E_a/ 2.303R and intercept value equals to log A.

(ii) The plot gives a negative slope straight line also.
(iii) From the slope of straight line, E_a can be calculated.

Total number of atoms per unit cell in a fcc structure = 4 atoms.

(i) An anionic complex compound contains a complex anion and simple cation.

(ii) A cationic complex contains complex cation and simple anion
