Question

И в алкенах и алкинах 1 все атомы углерода находиться в sp2 гибридном состоянии 2 присутствуют п связи в молекуле 3 отсутствует о связи 4 все связи углерод-углерод имеют одну постоянную длину Фенол взаимодействует с каждый из двух веществ 1 HBr и KOH 2 O2 и СО2 3 N2 и NaOH 4 KOH и Br2

Answer 1

1_ 2) так как  есть двойная и тройная связь

2_  4 

Answer 2

Alkenes and Alkynes

In both alkenes and alkynes, the carbon atoms are in sp2 hybridized state This means that each carbon atom in these molecules forms three sigma bonds and has one unhybridized p orbital perpendicular to the plane of the molecule The presence of the unhybridized p orbital allows for the formation of pi bonds in the molecule.

Phenol Interactions

Phenol can interact with several substances, including:

1. HBr and KOH: Phenol can react with hydrogen bromide (HBr) and potassium hydroxide (KOH). 2. O2 and CO2: Phenol can interact with oxygen (O2) and carbon dioxide (CO2). 3. N2 and NaOH: Phenol can react with nitrogen gas (N2) and sodium hydroxide (NaOH). 4. KOH and Br2: Phenol can interact with potassium hydroxide (KOH) and bromine (Br2).

Please note that the specific reactions and products formed in these interactions may vary. If you would like more information about the reactions, please let me know!
