Which of the following would react most readily with nucleophiles?

Detailed Solution for Test: Chemistry Mock Test - 5 - Question 1

 Nucleophile always attack on electron deficient site Presence of electron withdrawing groups such as NO,, t 11(3 etc., decieases the electron density on benzene nucleus, hence such groups activate the ring towards nucleophilic attack.
While presence of electron releasing groups such as - R or OR increases the electron density, thus deactivates the benzene nucleus toward nucleophilic attack Hence, NO, group activates the ring more than —Cl towards nucleophilic attack 
Thusreacts (rapidly) with nucleophiles.

The ratio of the molar amounts of H₂S needed to precipitate the metal ions from 20 mL each of 1M Cd(NO₃)₂ and 0.5 M CuSO₄ is
Detailed Solution for Test: Chemistry Mock Test - 5 - Question 5
As Cd2+ and Cu2+, both are dipositive ions but Cu2+ has one half of the concentration compared to that of the Cd2+. Thus, the molar amount of the H2S used to precipitate the metals ions Cd2+ and Cu2+ is 2 : 1.

In which of the following case,does the reaction go farthest completion ?
Detailed Solution for Test: Chemistry Mock Test - 5 - Question 9

∵ higher the equilibrium constant , fastest the rate of reaction to completion.
for understanding this concept let see one example .
A + B ⇄ C + D
Equilibrium constant , K = [C][D]/[A][B]
For fastest completion of reaction numerator of RHS will be higher the denominator . Means higher the numberator , higher will be equilibrium constant and higher will be rate of reaction to completion.

The atomic radius of elements of which of these would be nearly same
Detailed Solution for Test: Chemistry Mock Test - 5 - Question 14
The atomic radii of the d- block elements of a given series decrease with increase in atomic number but this decrease becomes small after midway. The decrease in atomic radii in the beginning, is due to an increase in nuclear charge from member to member which tends to reduce the size. At the same time, the addition of extra electrons to (n-1)d orbitals also provides the screening effect. As the number of d-electrons increases, the screening effect increases. Thus, there are operating two effects namely screening effect and nuclear charge effect which oppose each other. In the midway onwards of the series both these effects become nearly equal and thus, there is no change in atomic radii inspite of the fact that atomic number increases gradually.
