The correct order of stabilities of the following resonance structures is : (I) H_2 C = overset (oplus) N = overset (Ө) N (II) H_2 overset (oplus) C - N = overset (Ө) N (III) H_2 overset (Ө) C - overset (oplus) N -= N (IV) H_2 overset (Ө) C - N = overset (oplus) N .

The increasing order of pK_b value of the following is : (I) HC -= C^(Ө) H^(Ө) overset (Ө) NH_2 (IV) C overset (Ө) H_3 .

The increasing order of pK_b value of the following is : (I) HC -= C^(Ө) H^(Ө) overset (Ө) NH_2 (IV) C overset (Ө) H_3 .

Give the product and find out which is faster ? (a) (i) CH_3 CH_2 I overset (overset (Ө) OH) rarr (ii) D_3 C-CH_2 I overset (overset (Ө) O H) rarr (b) Give the product and find out which is faster out of SN^1 and E1 and why ? (i) (CH_3)_3 C C1 overset (overset (Ө)O H)rarr (ii) (CD_3)_3 C-C1 overset (overset (Ө) O H)rarr .
