Types of chemical reactions in organic chemistry (for example, hydrocarbons).

1) All organic matter burns with the formation of carbon dioxide and water. This reaction also refers to complete oxidation reactions. For instance:
CH4 + 2O2 = CO2 + 2H2O
2) Oxidation reaction.
For instance:
2CH3 – CH3 + O2 = 2CH3 – CH2 – OH
3) a) For saturated hydrocarbons (alkanes), substitution reactions (interaction with halogens) are characteristic:
СН3 – СН3 + Cl2 → СН3 – СН2 Cl + HCl
b) unsaturated hydrocarbons – alkynes can also enter into the substitution reaction:
СН Ξ СН + Ag2O → Ag С Ξ С Ag + Н2О
4) For unsaturated hydrocarbons (alkenes and alkynes), addition reactions at the site of breaking multiple bonds (double or triple) are characteristic. Can join: halogens (Cl2, Br2, I2), water (H2O), hydrogen (H2), hydrogen halides (HCl, HBr, HI)
CH2 = CH2 + Br2 → CH2 Br – CH2 Br
CH Ξ CH +2 Br2 → CH Br2 – CHBr2
CH2 = CH2 + H2O → CH3 – CH2OH
CH Ξ CH + H2O → CH3CHO
CH2 = CH2 + H2 → CH3 – CH3
CH Ξ CH + H2 → CH2 = CH2
CH2 = CH2 + HBr → CH3 – CH2 Br
CH Ξ CH + HBr → CH2 = CH Br
