Question

question 3 (1 point)
what type of organic reaction is the following:
chloroethane + naoch₂ch₃ →
elimination
combustion
substitution
addition
question 4 (1 point)
which type of organic reaction is the following:
propane + oxygen gas -->
hydrolysis
esterification
combustion
oxidation

Explanation:

Question 3

In the reaction of chloroethane (\(CH_3CH_2Cl\)) with \(NaOCH_2CH_3\), the \( - OCH_2CH_3\) group replaces the \( - Cl\) group. In substitution reactions, one atom or group of atoms in a molecule is replaced by another atom or group of atoms.

When propane (\(C_3H_8\)) reacts with oxygen gas (\(O_2\)), it is a combustion reaction. Combustion reactions of hydrocarbons involve the reaction of a hydrocarbon with oxygen to produce carbon dioxide (\(CO_2\)) and water (\(H_2O\)) (and heat). Hydrolysis involves reaction with water, esterification is the formation of an ester (usually from an alcohol and a carboxylic acid), and while combustion is a type of oxidation reaction, the more specific and common - name for the reaction of a hydrocarbon with \(O_2\) is combustion.

Answer:

C. substitution
