Question

CH3 - CH2 - CH - CH3 + NaOH→                           |                        OH

Answer 1

CH3 - CH2 - CH - CH3 + NaOH → CH3 - CH2 - CH - CH3 + H2O
                         |                                                             | 
                        OH                                                        ONa
                         
           а вообще основания со спиртами не вступают в реакцию             

Answer 2

The reaction you've provided appears to be the reaction of an alkane with sodium hydroxide (NaOH). Here's the balanced chemical equation for this reaction:

CH3-CH2-CH-CH3 + NaOH → CH3-CH2-CH2-CH3 + H2O

In this reaction, sodium hydroxide (NaOH) reacts with the alkane to form an alcohol and water. The sodium hydroxide (NaOH) is a strong base and it deprotonates one of the hydrogen atoms from the alkane, resulting in the formation of an alcohol (CH3-CH2-CH2-CH3) and water (H2O).

The specific alkane you've provided is butane (C4H10), and the reaction converts it into 1-butanol (C4H9OH).
