What alcohols do you need to take to obtain the following aldehydes: a) dimethylpropanal b) 2-methylbutanal

What alcohols do you need to take to obtain the following aldehydes: a) dimethylpropanal b) 2-methylbutanal c) hexanal. Write down the equations of the corresponding reactions

Aldehydes are derivatives of alcohols.
a) H3C – C (CH3) (CH3) – CH2OH + CuO = H3C – C (CH3) (CH3) – CHO + CuO + H2O;
The oxidation reaction of alcohol is dimethyl propanol. The reaction product aldehyde is dimethyl propanal.
b) H3C – CH (CH3) – CH2 – CH2 – OH + CuO = H3C – CH (CH3) – CH2 – CHO + Cu + H2O;
2 – methyl butanol 2 – methyl butanal
c) H3C – H2C – H2C – H2C – H2C – H2C – OH + CuO = H3C – H2C – H2C – H2C – H2C – CHO + Cu + H2O;
hexanol – alcohol hexanal – aldehyde
Aldehydes are essential for the synthesis of carboxylic acids.
