34. How many s-sp3 bonds are there in the following substance? A) 3 B)8 E) 16 C) 12 D) 13 35. Select the rate law for the following reaction, e.g. (RBr) A) Rate k [RBr] B) Rate [RBr] [OH ] C) Rate k [RBr (OH] Which is the strongest acid? A) CH CH OH D) Rate k [RBr] [OH E Rate k [RBr [OH 36. B) CH,CO2H C) HC CH D) CH2=CH2 E) CH3CH 37. What functional group is present in the following compound? Br A) 1° alkyl halide B) 2° alcohol C) 20 alkyl halide D) 1° amine E) 30 alkyl halide 38. What is the index of hydrogen deficiency (or degree of unsaturation) of benzene (CsH6)Y? A) 2 ) C) 4 D) 5 E) 6

Explanation / Answer

34) Number of s-sp3 bonds = 13 ( all sp3 C-H bonds are counted)

35) Rate = k [ RBr] [OH-] ( its 2nd order reaction since we had strng nucleophile OH-)

36) Strongest acd is CH3CO2H ( since its conjugate base CH3CO2^- is most stabilised by resonance , strong acid has more stable conjugate base )

37) we had 2 alkyl halide ( since halide Br is attached to secondary carbon)

38) Index of hydrogen defiecieny in benzene C6H6 is 4 ( we use formula dn = ( nC x 2+2 - nH) / 2, where nC = 6 , nH = 6 , dn value we get 4)
