Check the following questions asked this year.
Ans. The order of reaction here is a zero-order reaction.
Ans. For second-order kinetics, Rate= k[A]2. In case the concentration of A increases by 3 times, the rate of formation of B by this formula the rate of formation of B increases 9 times.
Ans. The expression of the integrated rate equation for the zero-order reaction
A → Products is
a) Ethanol, Propanone, Propanol, Butanone (reactivity towards nucleophilic addition)
Ans. The +I effect of the alkyl group increases in the order
Ethanal < Propanal < Propanone < Butanone
b) 4-Nitrobenzoic acid, benzoic acid, 3,4 Dinitrobenzoic acid, 4-Methoxybenzoic acid (Acid strength)
Ans. The strength of the given acid increase as 4-Methoxy benzoic acid < Benzoic acid < 4-Nitrobenzoic acid < 3, 4-Dinitrobenzoic acid.
Ans. Wolf Kishner Reaction is an indirect reduction of an aldehyde or ketone to the corresponding hydrocarbon due to the effect of heat on the hydrazone or semicarbazone derivative with an alcoholic solution of sodium ethoxide or with solid potassium hydroxide.
Cannizzaro Reaction: As per the definition the Cannizzaro reaction involves the reaction of aldehydes with caustic alkali in which one molecule of aldehyde is reduced to the corresponding alcohol and another molecule is oxidized to the salt of the corresponding acid.
