For the following questions answer them individually

Question 31

Consider a reaction $$aG + bH \rightarrow$$ Products. When concentration of both the reactants G and is doubled, the rate increases by eight times. However, when concentration of G is doubled keeping the concentration of H fixed, the rate is doubled. The overall order of the reaction is

Video Solution

Question 32

STATEMENT-1: Alkali metals dissolve in liquid ammoniato give blue solutions.
because
STATEMENT-2: Alkali metals in liquid ammonia give solvated species of the type $$[M(NH_3)_n]^{+}$$ (M = alkali metals).

Video Solution

Question 33

STATEMENT-1: Glucose gives a reddish-brown precipitate with Fehling’s solution.
because
STATEMENT-2: Reaction of glucose with Fehling’s solution gives CuO and gluconic acid.

Video Solution

Question 34

STATEMENT-1: Molecules that are not superimposable on their mirror images are chiral.
because
STATEMENT-2: All chiral molecules have chiral centres.

Video Solution

Question 35

STATEMENT-1: Band gap in germanium is small.
because
STATEMENT-2: The energy spread of each germanium atomic energy level is infinitesimally small.

Video Solution

Question 36

Among the following, identify the correct statement.

Video Solution

Question 37

While $$Fe^{3+}$$ is stable, $$Mn^{3+}$$ is not stable in acid solution because

Video Solution

Question 38

Sodium fusion extract, obtained from aniline, on treatment with iron(II) sulphate and $$H_2SO_4$$ in presence of air gives a Prussian blue precipitate. The blue colour is due to the formation of
