Chemistry Paper 2
Q 1. The spin only magnetic moment value (in Bohr magneton units) of is
(C ) 4.90
CO being strong legand forms inner orbital complex.
Q 2. In the following carbocation, is most likely to
migrate to the positively charged carbon is
(D) H at C-2
Q 3. For a first order reaction , the temperature (T) dependent rate constant (k) was found to follow the equation The preexponential factor A and the activation energy respectively, are
Q 4. The correct stability order of the following resonance
(A) (I) > (II) > (IV) >
(B) (I) > (III) > (II) > (IV)
(C ) (II) > (I) > (III) > (IV)
(D) (III) > (I) > (IV) > (II)
Smaller the separation of opposite charge greater is the stability 1st structure is more stable because of the fact that -ve charge existing on the electronegative atom.
