Important List of Reaction Mechanism Formulae | Reaction Mechanism Formula Sheet

This section is included with the full list of Reaction Mechanism Formulas. So, students are advised to refer and get the Reaction Mechanism Formulae sheet & tables offline from this page. Make use of these formulas as a reference throughout your preparation and get the know the concepts adequately. Also, apply them properly to make your job simple & easy. 

1. Stability order of free radicals
(C6H5)\(\dot{\mathrm{C}}\) > (C6H5)2\(\dot{\mathrm{C}}\)H > C6H5\(\dot{\mathrm{C}}\)H2 > \(\dot{\mathrm{C}}\)H2 = CH – \(\dot{\mathrm{C}}\)H2 > (CH3)3\(\dot{\mathrm{C}}\) > (CH3)2 \(\dot{\mathrm{C}}\)H > CH3 \(\dot{\mathrm{C}}\)H2 > \(\dot{\mathrm{C}}\)H3 > CH2 = \(\dot{\mathrm{C}}\)H

2. Stability order of carbonium ions
(C6H5)3 \(\stackrel{\oplus}{C}\) > (C6H5)2 \(\stackrel{\oplus}{C}\)H > C6H5 \(\stackrel{\oplus}{C}\)H2 > CH2 = CH – \(\stackrel{\oplus}{C}\)H2 > ter. carbonium ion
> sec. carbonium ion > prim. carbonium ion

3. Stability order of Carbanions
(C6H5)3\(\stackrel{\ominus}{C}\) > (C6H5)2\(\stackrel{\ominus}{C}\) > C6H5\(\stackrel{\ominus}{C}\)H2 > CH3CO\(\stackrel{\ominus}{C}\)H2 > CH2 = CH – \(\stackrel{\ominus}{C}\)H2 and \(\stackrel{\ominus}{C}\)H3 > CH3\(\stackrel{\ominus}{C}\)H2 > (CH3)2\(\stackrel{\ominus}{C}\)H > (CH3)3\(\stackrel{\ominus}{C}\)

4. -I effect order
NO2 > – CN > COOH > F > Cl > Br > I > – OCH3 > -OH > -C ≡ C- > Reaction Mechanism formulas img 1 > H

5. + I effect order
(CH3)3C > (CH3)2CH > CH3CH2 > CH3

6. Electromeric effects occurs in molecules which contain a multiple bond i.e.
>C = 0, -C ≡ N, >C = C<, – C ≡ C-

7. +M effect is shown by following groups
-OH, -OR, – \(\stackrel{\ominus}{O}\) , – NH2, – NHR. – NR2, -Cl, -Br. – I etc.

8. Order of reactivity of double bonds towards electrophilic additions is –
CH2 = CH-COOH < CH2 = CH2 < CH3-CH = CH2
< CH3 – CH = CH2 < (CH3)2 C = CH2 < (CH3)2 C = CH-CH3
< (CH3)2C = C (CH3)2
