дописать реакции:пропанол-2+Na->?????дегидратация 2-метилпентанола-1????бутанол-1+Cu0(под нагреванием)->??????бутанол-2+CuO(под нагреванием)-> ?????

Answer 1

1. 2СН3СН(ОН)СН3 + 2Na = 2CH3CH(ONa)CH3 + H2

2. CH3CH2CH2CH(CH3)CH2OH --H2SO4/>150 C--> CH3CH2CH2C(CH3)CH2 + H20

3. C4H9OH + CuO = C3H7CHO + Cu + H2O

4. CH3CH2CH(OH)CH3 + CuO = CH3CH2COCH3 + Cu + H2O 

Answer 2

Reaction: Propanol-2 + Na -> ?????

The reaction between propanol-2 and sodium (Na) is known as a nucleophilic substitution reaction. In this reaction, the sodium (Na) acts as a strong nucleophile and replaces the leaving group (OH) in propanol-2, resulting in the formation of a new compound. The specific product formed will depend on the reaction conditions and the presence of any other reagents or catalysts. Without further information, it is difficult to determine the exact product of this reaction.

Dehydration of 2-Methylpentanol-1

The dehydration of 2-methylpentanol-1 involves the removal of a water molecule from the alcohol compound. This reaction typically requires the use of an acid catalyst, such as concentrated sulfuric acid (H2SO4) or phosphoric acid (H3PO4). The acid catalyst helps to facilitate the removal of the hydroxyl group (OH) from the alcohol, resulting in the formation of an alkene.

The specific product formed in the dehydration of 2-methylpentanol-1 will depend on the position of the hydroxyl group in the molecule. Since 2-methylpentanol-1 has a primary alcohol group (OH) attached to the first carbon atom, the dehydration reaction will result in the formation of 2-methyl-1-pentene.

Reaction: Butanol-1 + Cu0 (under heating) -> ?????

The reaction between butanol-1 and copper (Cu) under heating conditions is known as a catalytic hydrogenation reaction. In this reaction, the copper (Cu) acts as a catalyst, facilitating the addition of hydrogen (H2) to the double bond in butanol-1. This results in the formation of a new compound.

The specific product formed in this reaction will depend on the reaction conditions and the presence of any other reagents or catalysts. Without further information, it is difficult to determine the exact product of this reaction.

Reaction: Butanol-2 + CuO (under heating) -> ????

The reaction between butanol-2 and copper oxide (CuO) under heating conditions is known as a dehydrogenation reaction. In this reaction, the copper oxide (CuO) acts as a catalyst, facilitating the removal of hydrogen (H2) from butanol-2. This results in the formation of a new compound.

The specific product formed in this reaction will depend on the reaction conditions and the presence of any other reagents or catalysts. Without further information, it is difficult to determine the exact product of this reaction.
