Differentiate SN1 and SN2 reaction mechanism.

I need these two answered

what are the difference between SN1 and SN2 reaction ? describe the reaction mechanism difference between SN1 and SN2 and give examples with specific detailed explanation.

Show step by step mechanism

Please answer ASAp with detailed explanation

Compound D, shown below, reacts with hydrogen bromide by electrophilic addition. A mixtur organic compounds, E and F, is formed. CH₂CH3 CH3 CH₂ HBr Time left 0:45:55 Mixture of organic compounds E and F H compound D (i) Name the the two organic compounds E and F and show their condensed formula. (ii) Briefly explain the mechanism of the reaction between compound and hydrogen bromide to form either compound E or compound F. You can listature the main dept) (ii) Which comprand. E or F is the major product

Select the properties of the SN2SN2 reaction mechanism

Pls help ASAP.

Propose a reasonable mechanism

summarize in a table how SN2 type reactions are characterized in terms of the following criteria: (1) choice of nucleophile; (2) substrate (RX); (3) solvent; (4) kinetics (order of reaction and rate law); (5) stereochemistry; (6) possibility of rearrangements.
