Write the color of your test on the an awer sheet -CH (A) sp3, sp, sp2 (D) sp2, sp, sp3 (B) spa, sp2, sp (E) sp, sp, sp3 (C) sp, sp2, sp 2 Formal charges of atoms x and y are: (A) O and-1 (B) -1 and+1 (C) +1 and-1 (D) -1 and o (E) 1 and The chemical formula of the molecule shown below is: (C) CBHieN2O (A) CoioNOs (D) C,H 4N20 (B) (E) C,H 4NO2 H O 4. The degree of unsaturation of the molecule shown in Q3 is: (C) 3 (D) 5 (E) 6 (A) 1 (B) 2 5. The functional groups of the molecule in Q3 from left to right are: (B) amine, amide, ester (D) amine, amide, ether (A) amide, amine, carboxylic acid (C) amine, amide, carboxylic acid (E) amine, ketone, amine, ester 6. Arrange the following cations in order of increasing stability ?? ? (C) IllExplanation / Answer
1 Ans (D) sp2, sp and sp3
2. Ans (C) +1 and -1
Formal Charge = [No of valence electrons on atom] – [non-bonded electrons + number of bonds].
formal charge of O (x) = 6 - (2+3) = +1
formal charge of B (y) = 3-(0+4) = -1
3.Ans (D) C8H14N2O3
4. Ans (B) 2
presence of 2 double bonds
5. Ans (B) amine amide ester
6. Ans (B) II<I<III
the order of stability of carbocations primary<secondary<teritary
7 Ans (B) (Z)-2Bromo-2-pentene
