Need HELP ASAP!!!

For each of the following series of carbocations rank them in order of increasing stability from least stable to most stable. 1. H CH2 CH2 H H H A B D [1 mark] . 2. HH H A A B [1 mark] 4 In your last laboratory experiment you performed the following reaction: N CH, HNO3, H2SO4 N CH, ON Acetanilide (a) What is the electrophile that reacts with the aromatic ring? [1 mark] (b) Complete the following equation for the formation of the electrophile in part (a) HNO3 + H2SO4 + HSO. (1 mark) (c) Using curly arrows, draw the mechanism of the substitution of the electrophile with acetanilide to form the product Consider the following electrophilic addition reaction: H-C1 carbocation 1 carbocation 2 product A product B (a) For each carbocation indicate if it is primary, secondary or tertiary [2 marks] (b) Indicate which, if either of the carbocations is the most stable [1 mark] (c) Indicate which of the two products would be the major species obtained and invoking Markovnikov's rule, explain why
