Unless otherwise instructed, you may use the periodic table in the Chemistry: Problems and Solutions book for this question.
Aleks [24]

Answer:

The electronegativity differences between carbon and oxygen are not very large.

Explanation:

Between the atoms of carbon monoxide exists a covalent bond which attaches the carbon to the oxygen.

In this type of bonding, both atoms shares a given number of valence electrons to attain chemical stability.

A substance is polar when there is a distinct charge separation between the species.

For covalent bonds, the electronegativity difference plays in important role in determining the polarity of the compound. When the difference is large, the compound will be polar but when the difference is very small or zero, no polarity will exist.

In between carbon and oxygen of carbon monoxide, the electronegativity difference is very low.

Draw the carboxylic acid produced from the acid hydrolysis of butyl acetate.
Nat2105 [25]

Answer:

Acetic or ethanoic acid.

Explanation:

Hello,

Butyl acetate's hydrolisis is shown below:

CH_3COOCH_2CH_2CH_2CH_3+H_2O-->CH_3COOH+CH_3CH_2CH_2CH_2OH

Whereas CH_3COOCH_2CH_2CH_2CH_3 is the butyl acetate, CH_3CH_2CH_2CH_2OH butanol and CH_3COOH the required produced acid, acetic or ethanoic acid (attached picture).

Best regards.
